N-able N-central System requirements
The following requirements are for typical usage patterns, acknowledging that some patterns may require
greater system resources for a N-able N-central server than others.
If you have any questions about how your needs affect the system requirements of your N-able N-central
Processor Server class x86_64 CPUs manufactured by Intel or AMD (i.e. Xeon or EPYC). Please refer to
the Red Hat Hardware Ecosystem for further details.
Operating
System
You do not need to install a separate Operating System to run N-able N-central. The N-able
N-central ISO includes a modified version of CentOS 7, based on the upstream Red Hat
Enterprise Linux 7.
Physical
Hardware
The physical server used to install N-able N-central in a bare metal environment must be
certified to run Red Hat Enterprise Linux 7.7 (x64) by Red Hat, or the hardware vendor,
without any additional drivers. Please check the Red Hat Hardware Ecosystem for details.
Server Grade hard drives connected to a RAID controller with a Battery/Capacitor Backed
Cache are Required. Examples include 10K+ RPM SCSI or SAS drives, Enterprise Grade SSDs
or NVMes for bare metal and virtualized hosts, or a Fibre Channel connected SAN with
Enterprise Grade hard drives for virtualized hosts
(Fibre Channel cards can be used for bare
metal if they are configured in the pre-boot environment and do NOT require vendor-
provided drivers)
.
Although Desktop Hard Drives will work with the Operating System, they do not meet the
minimum throughput required for the back-end Database of N-able N-central.
For more details, please refer to the Red Hat Hardware Ecosystem to see if your current hardware will work with
our customized version of CentOS 7.
System requirements by number of devices managed
The table below lists the minimum specifications required to manage the number of devices indicated (based
on average usage). Performance can be improved by exceeding these requirements. When determining your
hardware requirements, consider any growth in managed device count that may occur over time.
Number of Devices CPU Cores Memory Storage
Up to 1,000 2 4 GB RAM 80 GB RAID
Up to 3,000 4 8 GB RAM 150 GB RAID
Up to 6,000 8 16 GB RAM 300 GB RAID
page 12
Number of Devices CPU Cores Memory Storage
Up to 9,000 12 24 GB RAM 450 GB RAID
Up to 12,000 16 32 GB RAM 600 GB RAID
Up to 16,000 22 48 GB RAM 800 GB RAID
Up to 20,000 28 64 GB RAM 1 TB RAID
Up to 24,000 34 80 GB RAM 1.2 TB RAID
Notes
1. Server Grade hard drives connected to a RAID controller with a Battery/Capacitor Backed Cache, are
required to ensure performance and unexpected power-loss data protection.
2. In a virtualized environment, hard drives for the N-able N-central server must not be shared with any
other applications or VM guests that have significant I/O workloads. For example, Report Manager, SQL
Databases, E-Mail Servers, Active Directory Domain Controllers, SharePoint, or similar should not be
installed on the same physical hard drive as N-able N-central.
3. N-able recommends two or more hard drives be placed in a redundant RAID configuration. With two
drives, RAID 1 must be used. With more than two drives, RAID 1+0 or RAID 5 are recommended. RAID 6 is
an option on servers with less than 1,000 devices (the additional write latency of RAID 6 becomes an
issue above 1,000 devices).
4. N-able recommends more, smaller disks in a RAID array, as opposed to fewer larger disks. Database-
backed applications, like N-able N-central, have better write performance with an increased number of
parallel writes (hard drives).
5. If using Solid State Drives (SSDs), N-able requires Enterprise Grade, SLC based (or better) SSDs with a
SAS interface, or Enterprise Grade NVMes. SSD and NVMe drives must have an endurance rating of at
least 0.2 DWPD (Drive Writes Per Day), and at least 2 physical disks in a redundant RAID array. On Bare
Metal servers, the RAID array must appear to the operating system as a single Block or NVMe Device.
Currently, many PCIe and NVMe drives do not meet this last requirement and would only work in a
virtualized environment.
6. Configure the RAIDcontroller to use the default stripe size and a Read/Write cache of 50%/50%.
The underlying customized version of CentOS 7 has certain hardware limits that are consistent with the
upstream Red Hat Enterprise Linux 7 distribution. Of note are the following:
Subsystem Limit
Minimum disk space 80GB
Maximum physical disk size (BIOS) 2TB
Maximum physical disk size (UEFI) 50TB
page 13
Subsystem Limit
Required minimum memory 4GB for 4 or fewer logical CPUs
1GB per logical CPU for more than 4 logical CPUs
Maximum memory 12TB
Maximum logical CPUs 768
Examples of supported servers
Due to the ecosystem of different hardware, N-able does not certify specific hardware configurations. Instead
we rely on the upstream Red Hat Enterprise Linux and hardware vendor testing and certification.
Examples of servers that have been Red Hat certified include HPE ProLiant DL360 Gen10 and Dell PowerEdge
R620.
Please consult with your hardware vendor to ensure that any server to be used for a bare metal installation
meets the above requirements, and is Red Hat Enterprise Linux 7.7 certified, without the need for additional
drivers.
N-able recommends that for any Bare Metal server, two or more SAS 10k or faster hard drives be placed in a
RAID array to improve redundancy. RAID 1+0 or RAID 5 are supported (at the hardware RAID BIOS level). RAID 6
is an option on servers with less than 1,000 devices (the additional write latency of RAID 6 becomes an issue
above 1,000 devices).
page 14
Support for virtualized environments
N-able supports VMware ESX Server 6.0 or newer and Windows Server 2012 R2 Hyper-V or newer LTS versions.
N-able recommends use of the latest stable versions of VMware or Hyper-V in order to ensure the best
performance, feature set and compatibility with N-able N-central.
Hyper-V on Windows Desktop Operating Systems not Supported.
N-able N-central installed on a virtual machine running on a Desktop Operating System (such as Hyper-
V on Windows 10, Virtual Box, Parallels, VMWare Fusion or similar) is not a supported configuration. If
you are using Windows Hyper-V, it must be installed on a supported server class Windows Operating
System.
Windows Server Semi-Annual Releases are not Supported.
Only Long-Term Support (LTS) versions of the Windows Server Operating System are supported as a
Hyper-V host for N-able N-central. Microsoft currently releases "Semi-Annual Release" versions of
Windows Server as a technology preview for the next LTS version. Due to their technology preview
status, these "Semi-Annual Release" versions of Windows Server are not supported as Hyper-V hosts
for N-able N-central.
About virtualization
Virtualization provides an abstraction layer between the hardware and the Operating System which permits
the operation of multiple logical systems on one physical server unit. The table below includes considerations
when using this deployment method.
System
Performance
It is impossible to guarantee the scalability or performance of a N-able N-central server
deployed on a Virtual Machine due to:
n
variability in field environments resulting from host server configurations,
n
the number of virtual guests run on the host server, and
n
the performance of the underlying host hardware.
Supportability N-able supports N-able N-central software deployed on VMWare ESX/ESXi 6.0 or newer,
Windows Server 2012 R2 Hyper-V or newer LTS releases, Microsoft Azure and Amazon
AWS EC2 in the same way that we support N-able N-central deployed on Bare Metal.
This support is limited to the components (Software and Operating System) shipped
with N-able N-central and does not include the troubleshooting of virtualization
systems nor of performance issues related to environmental factors.
page 15
N-able recommends reaching out to your hardware or virtualization vendor for support
on the underlying virtualization and hardware components. Any assistance provided by
N-able Support for virtualization or hardware issues is on a best-effort basis only. In the
event of serious performance problems, we might ask you to migrate a virtualized N-
able N-central system to a physical hardware deployment.
Virtual
Hardware
Support
In Windows Server 2016 Hyper-V or newer deployments, it is recommended to create a
new Generation 2 VM. When configuring the VM virtual hardware, if you choose to
enable Secure Boot, please select the Microsoft UEFI Certificate Authority template.
For VMWare ESX/ESXi deployments, it is recommended to select the Red Hat
Enterprise Linux 7 guest OS template, then under the Boot Options, select the UEFI
Firmware.
Network
Adapters
N-able recommends using the VMXNET3 network card in VMWare. When the VM is
configured as Red Hat Enterprise Linux 7, it will use VMXNET3 by default.
Unless you are using Network Interface Bonding, N-able N-central requires only one (1)
network adapter added to the VM configuration. Multiple network adapters that are not
used in a bonding configuration can cause connectivity and licensing issues.
MAC Addresses By default, most virtualization environments use a dynamically assigned MAC address
for each virtual network card. As your N-able N-central license is generated in part by
using the MAC address of its network card, it is required to use a statically assigned
MAC address in order to avoid becoming de-licensed.
Recommended configuration for the virtualized server
Although provisioning virtual disks as "thin" or "thick" results in nearly-identical performance, thick
provisioning is recommended, particularly when more than 1,000 devices will be connected to your N-
able N-central server.
n
Assign the highest resource access priority to N-able N-central, as compared to other guest VMs.
n
Do not over-provision resources (Memory, CPU, Disk) on the virtualization host. Over-provisioning these
resources can causes memory swapping to disk, and other bottlenecks that can impact guest system
performance.
n
Ensure that the system has enough RAM and hard drive space to provide permanently allocated
resources to the N-able N-central guest.

Prepare installation media
To install N-able N-central on a bare metal server, without the option to upload a disk image through iLO, iDRAC
or IMM2, you will need to prepare a DVD, or a USB Flash Drive with the N-able N-central installer image.
DVD Creation
Follow the directions for your DVD creation software to burn the N-able N-central .iso to disk.
USB Flash Drive
For the USB Flash drive to properly install N-able N-central on both BIOS and UEFI systems, you need to write
the .iso image to disk using the “DD” disk writing method. The USB Flash Drive must be at least 2GB in size. You
will not be able to use any extra space on the drive until after N-able N-central is installed and you reformat the
drive.
This process is a destructive process for the USB Flash Drive. All data on the USB Flash Drive will be
erased.
Linux and MacOS
1. Elevate to the root user so you can mount the USB Flash Drive.
sudo su –
2. Identify the USB Flash Drive device name. Be careful to verify the device size so you don’t accidentally
overwrite another device, like you hard disk.
Linux: lsblk
MacOS: diskutil list
3. Write the disk image to the USB Flash Drive. Make sure the device you are writing to is your USB Flash
Drive. This step will overwrite all data on the drive. Be sure to specify the device name, not the partition
name (/dev/sdb, not /dev/sdb1).
dd if=/path/to/N-central.iso of=/dev/device-name bs=512k
Windows
Use a third-party utility, for example, Rufus, to write the disk image to your USB Flash Drive.
When copying the .iso file, ensure you use the following configuration options:
n
Partition scheme: “MBR”
n
Target system: “BIOS or UEFI”
n
Volume label: Leave it as is. Do NOT change the label!
n
File system: FAT32
n
Cluster size: Default
If you are asked to select the mode used to write the image to disk, use DD Image mode. If not
selected, N-able N-central may fail to install on certain devices.

Install N-able N-central on Microsoft Azure Managed Disks
The instructions below walk you through a new installation of N-able N-central in the Microsoft Azure Manage
Disks environment. Microsoft Azure Classic deployment is no longer supported, however, Azure Resource
Manager without Manage Disks is still supported.
While we recommend new deployments use this Azure Managed Disk deployment method, the 100GB, 200GB,
500GB and 1TB VHD images are still available for Azure Resource Manager without Managed Disks, and is
available and supported for reinstalling and restoring N-able N-central from a backup.
Unlike all other N-able N-central deployments, Azure Managed Disks (MD) deployments support/require at
least one Data disk in addition to the Operating System Disk. When you use the deployment script and assign
one Data disk, Azure creates a RAID 0 array of the one disk. If you assign
X
data disks, Azure creates a RAID 0 of
those
X
disks. N-able N-central uses a RAID 0 to combine multiple Data disks into a single mount point, while
writing to all disks in parallel. This increases the IOPS throughput by
X
times.
Additionally, Azure MD deployments have no SWAP Volume, as N-able N-central uses the Resource Disk for the
SWAP Volume. The Azure MD OS Disk image is 8 GB, as the install dynamically expands the image to match the
deployed Managed Disk size on first boot.
Azure MD images are published to each Public Azure Region, so you no longer need to upload the VHD. It is
important to know that there are some Azure Regions that are restricted to certain Azure users. These are a
second, geographically separated Azure Region in the same country, or in the case of the EU, another nearby
country that is reserved for customers needing in-country disaster recovery. For information on Azure regions,
see https://azure.microsoft.com/en-us/global-infrastructure/geographies/#overview.
Deployment
Deploying N-able N-central to Azure with Managed Disks is simplified by using a Deployment PowerShell script.
The script requires PowerShell 7 (formerly PowerShell Core) and the Azure PowerShell Module. You can run the
script on any operating system that supports the cross platform PowerShell 7.
You must have basic knowledge of how to use Microsoft Azure, Windows PowerShell and how to install
and configure N-able N-central.
The script is available for download on the N-able N-central release page of the N-able Partner Success
Center.
After downloading the PowerShell Script, you need to edit the settings at the top of the script to meet your
requirements. Some items are required, while others can be left with the defaults unless they need to use
specific values, such as the virtual network settings. The script contains full documentation explaining all
included options.
Ultra_SSD Data Disks are not supported.
page 34
Before you deploy a dual stack application in Azure, you must configure your subscription for this
preview feature using the following Azure PowerShell.
Register as follows:
Register-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -
ProviderNamespace Microsoft.Network
It takes up to 30 minutes for feature registration to complete.
You can check your registration status by running the following Azure PowerShell command:
Get-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -
ProviderNamespace Microsoft.Network
After the registration is complete, run the following command:
Register-AzResourceProvider -ProviderNamespace Microsoft.Network
Once you have modified the PowerShell Install Script with your settings, you only need to launch it in a
PowerShell console and it will complete the deployment for you. If you have not already logged into your Azure
account from PowerShell, the script will prompt you to log in.
If you are using Windows, you may need to complete the following steps to run the script. For more information
see the Microsoft article, Set-Execution Policy.
1. Ensure your PowerShell Execution Policy is set to "Remote-Signed".
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
2. Un-Block the Install Script.
Unblock-File -Path .\AzureMD.ps1
First run
After the PowerShell Script has completed successfully, wait a few minutes before logging into the Web UI. On
first run, N-able N-central will expand the OS disk, create a software RAID from the data disks, and move the
database to it, then reset the trial license. This process can take 10 - 15 minutes to complete.
If you try to log in to the web UI right after they VM is deployed, you will be kicked out, and the web UI will
be unresponsive for a few minutes while the first run tasks complete.
If you deploy the VM more than 15 days after the Azure image was generated, you will be able to tell the first
run activities have not been completed by the expired license warning on the login page. Once the first run
tasks complete, the license error will no longer be present.
VMSizing
Always size N-able N-central for your expected number of devices in the future. Try to plan for at least 2
- 3 years in the future.
page 35
The maximum number of supported Data Disks is defined by the Azure VM size. You will need to consult the
Azure Documentation for their VM size before deciding on the number of Data Disks. Azure VM sizing can be a
little tricky, and may require some trial and error to determine the best VM size for any particular deployment.
VM sizing must support Generation 2 VMs.
Rough guidelines are as follows:
Number of
Devices
Recommended Azure
Size CPUCores Memory OSDisk
Data
Disks
(Total)
Up to 1,000 Standard_DS2_v2 2 4 GB 80 GB 20 GB
Up to 3,000 Standard_DS3_v2 4 8 GB 110 GB 60 GB
Up to 6,000 Standard_DS4_v2 8 16 GB 200 GB 125 GB
Up to 9,000 Standard_DS5_v2 12 24 GB 300 GB 200 GB
Up to 12,000 Standard_DS5_v2 16 32 GB 400 GB 275 GB
Up to 16,000 Standard_DS32s_v3 22 48 GB 550 GB 375 GB
Up to 20,000 Standard_F32s_v2 28 64 GB 700 GB 500 GB
Up to 24,000 Standard_F48s_v2 34 80 GB 875 GB 650 GB
Notes
n
The recommendations are based on N-able N-central requirements balanced with Azure Maximum IOPS.
For example, N-able recommends "Standard_DS5_v2" as apposed to the newer generation "Standard_
D16s_v3", because the "Standard_DS5_v2" has a maximum IOPS of 51200 as compared to 25600 for the
"Standard_D16s_v3".
n
For best performance, we recommend using the maximum number of Data disks your VM size permits.
More small disks will provide better IOPS performance than fewer larger disks.
n
The OS disk is still used for temporary storage during the nightly backup to reduce IOPS on the data
disks, as well as for the Backup Volume. Therefore there needs to be at least the size of the Data disk,
plus OS files, Repository and 15% for the Backup Volume. As a result, the total disk utilization is slightly
more than for non-Azure deployments.
n
N-able N-central is only supported on Instance types that provide local SSD storage. For Azure based N-
able N-central deployments, the Local SSD Resource Disk is used for the swap-file, in place of the swap
volume on all other N-able N-central deployments. An example of an unsupported instance type without
local SSD storage would be the Dsv4 Series (not to be confused with the supported Ddsv4 Series).
n
N-able N-central is only currently supported on Instance types that provide Intel Processors. The newer
AMD EPYC Processor instances have not been tested and verified. An example of an unsupported AMD
EPYC instance type would be the Dasv4 Series.

New: December 7, 2020
Deployment script for Microsoft Azure - Managed Disks
Deploying N-able N-central to Azure with Managed Disks is simplified by using a Deployment PowerShell script.
The script is available for download on the N-able N-central Release page of the N-able Partner Success
Center.
This script requires PowerShell 7.0 or higher. PowerShell 7 is a cross platform version of PowerShell (Formerly
called PowerShell Core) that has installers for Windows, MacOS and Linux. You can download the latest version
of Powershell on GitHub.
The script is pre-populated with the version of N-able N-central you downloaded it for. If you want to install a
different version, replace this value with the full Version number. The version is on the N-central Download
Page for the version you want to deploy.
Note that Azure Managed Disks are only supported for N-able N-central 2020.2 and higher releases.
For more information on the installation process, see Install N-able N-central on Microsoft Azure Managed
Disks.
Azure information
You can retrieve your Azure subscription ID from the Subscriptions Blade in the Azure Portal.
https://portal.azure.com/#blade/Microsoft_Azure_Billing/SubscriptionsBlade
Azure Region
Select the Azure region, for example, eastus where N-able N-central will be located. Not all features are
available in all regions. Check with Microsoft Azure for availability. You can get all the Azure locations using the
Azure PowerShell command:
Get-AzLocation
Resource naming prefix
The script is designed to use a naming prefix for naming all resources it creates. With the default script
configuration, keep this value between 1 - 18 characters, excluding any symbols to avoid exceeding other
resource name length limits.
For more information, see Develop your naming and tagging strategy for Azure resources.
VM size
You will need to define the size of the N-able N-central, Azure, Generation 2, VM Instance, for example,
'Standard_DS3_v2'. You can get all the VM sizes in the US East region using the Azure PowerShell command.
Use the region where you plan to install N-able N-central:
Get-AzVMSize -Location 'eastus'
For more information, see Support for generation 2 VMs on Azure.
page 38
Operating system disk size
You will need to define the size of the new OS Managed Disk in GB. It should be greater than 80GB. For more
information, see What disk types are available in Azure?
Operating system disk storage type
Select the storage type for the Operating System Managed Disk. The valid options are:
n
Premium_LRS,
n

n
Azure Storage redundancy
Data disks sizes
You will need to set the size of the new Data Managed Disks in GB (each). All the Data Disks will be combined
into a software RAID to take advantage of parallel disk writes, spreading the IOPs load across the total number
of disks you select.
Number of data disks
Define the number of Data Managed Disks in the Software RAID array. This value can be between 1 - 99, but the
maximum number of Data Disks is defined by the Azure VM Size.

Boot diagnostics storage account
Select the storage type for the Boot Diagnostics Storage Account. The valid options are:
page 39
n
Premium_LRS,
n
StandardSSD_LRS, and
n
Standard_LRS.
This storage account is used for the Azure VM boot diagnostic logs. It is also used during deployment to
temporarily host the VHD image before it is imported to a Managed Disk. This is a seldom used storage
account, so it does not have to be on the fasted storage types.
Boot diagnostics storage account type
Select the type of boot storage account you want to use for the VM Boot Diagnostics storage. N-able N-
central requires either Storage or StorageV2.
n
Storage: General purpose Storage account that supports storage of Blobs, Tables, Queues, Files and
Disks.
n
StorageV2: General Purpose Version 2 (GPv2) Storage account that supports Blobs, Tables, Queues,
Files, and Disks, with advanced features like data tiering.
Accelerated networking
TheN-able N-central image for Azure Managed Disks has been configured to support Accelerated Networking,
if desired. For more information, see Create a Linux virtual machine with Accelerated Networking using Azure
CLI.
IPv6 Support
N-able N-central does not yet support IPv6 for monitoring, however the underlying operating system and
services are ready to support it in the future. To future proof your deployment, you can configure the Azure
deployment with IPv6 support.
Before you deploy a dual stack application in Azure, you must configure your subscription for this preview
feature using the following Azure PowerShell commands:
Register-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -
ProviderNamespace Microsoft.Network
It takes up to 30 minutes for feature registration to complete. You can check your registration status by
running the following Azure PowerShell command:
Get-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -ProviderNamespace
Microsoft.Network
After the registration is complete, run the following command:
Register-AzResourceProvider -ProviderNamespace Microsoft.Network
You can generate a random Private IPv6 Network Prefix by going to https://simpledns.com/private-ipv6.

Upgrading N-able N-central
This document includes the following upgrade procedures:
n
Step 1: Back up the N-able N-central server
n
Step 2: Install the N-able N-central server upgrade
n
Step 3: Post-installation steps
There may also be circumstances when you want to rebuild or migrate your server.
See Rebuild or Migrate your N-able N-central server.
Refer to the release notes for compatible upgrade paths before you upgrade from one version to
another.
page 43
Step 1: Back up the N-able N-central server
Before you upgrade, back up the N-able N-central server in the event of an upgrade failure. Back up the server
to a destination FTPserver or, if N-able N-central has been installed as a guest on an ESX or Hyper-V server,
record a snapshot of the guest.
Pre-Backup Snapshot.
If you are running N-able N-central as a virtual machine, before upgrading, you may wish to create a
Snapshot of the virtual machine. In order to avoid corruption of the Snapshot due to database tables
being cached in memory, you will need to shut down the N-able N-central virtual machine before
creating the Snapshot.
N-able recommends shutting down the virtual machine and deleting the Snapshot after the upgrade
has completed successfully. Deleting the Snapshot will prevent increased disk write latency associated
with the differencing disks used by Snapshot technologies.
1. Click Administration > System Backup and Restore > Configure Backups and configure the backup
properties.
2. Click Save and Run Backup.
During the backup, a backup file and a backup digest file are created. The backup file contains all
of the information needed to restore the system. The SHA1 file contains a SHA1 checksum of the
backup file and verifies that the backup file is not corrupted.
3. Wait for the system to send you a notification about the backup success or failure.
4. If the backup succeeded and you have not configured it to be uploaded to an FTP server, download the
backup image from the N-able N-central server to a safe location:
a. Click Administration > System Backup and Restore > Download Backups.
b. Click Download Backup beside the name of the backup file you want to download and save it to a
known location.
c. (Optional) Click Download Digest beside the name of the backup file and save the digest file to a
known location.
The downloaded files can now be used to restore the database. To continue the upgrade, proceed to Step 2:
Install the N-able N-central server upgrade.
page 44
Step 2: Install the N-able N-central server upgrade
You can upgrade to N-able N-central 2022.5by installing the upgrade file downloaded to your N-able N-central
server or from the N-able Resource Center.
1. Log into the N-able N-central Administration Console using one of the following URLs:
n
https://
<Your Server Address>
/admin

5. Click Install.
If you selected the Remote Upgrade option, the .nsp file will now be uploaded to the N-able N-
central server.
Please upload the .nsp upgrade file from a machine local to the N-able N-central server in order to
avoid a file upload timeout on a slow internet connection.
Once the .nsp file is uploaded, or if you are installing from the local repository, the upgrade file will
now be extracted to the N-able N-central server. This can take a few moments.
6. Click Confirm to begin the install.
The N-able N-central Web UI and services will be stopped and the upgrade will be applied.
You can monitor the progress of the N-able N-central upgrade from the server console.

Rebuild or Migrate your N-able N-central server
There may be circumstances when you want to rebuild or migrate your server. For example:
n
Your N-able N-central server is not functioning properly or starting successfully;
n
An upgrade has failed but you can still log in to N-able N-central;
n
You are migrating an existing N-able N-central server to another computer.
The following scenarios describe the best way to rebuild or migrate your N-able N-central server.
The server is not working properly or starting successfully
1. Verify the version of your N-able N-central server. Technical Support can confirm the version of N-able N-
central that last communicated with N-able if your server is not working properly or cannot be restarted.
