Migrating via Migration Assistant does not transfer your Synology Account and licenses. Some services also require manual configuration after migration. If you use such services on the source NAS, follow the steps in this article to configure the destination device to take over the services from the source NAS.

After the migration task has succeeded, block the connection to the source NAS until the destination NAS is ready to provide services. Doing so prevents data inconsistency. To stop the services on the source NAS, try either of the following:

• Disable the network interface that provides services to all users. In the meantime, you can enable another network interface for yourself to manage and monitor the source NAS.
• Disable all connection methods (e.g., QuickConnect, IP, Domain name services) for all users.

1. Re-configure non-migratable settings

3.1 Repair and update packages

• If the source and destination NAS use different CPU and package architectures, you must go to Package Center on the destination NAS to repair all packages. Learn more about CPU and package architecture of the models in this article.
• When migrating between two Synology NAS with different DSM versions, some packages' versions on the source NAS may not be compatible with the DSM version of the destination NAS, and require an update after the migration task is finished. Go to Package Center on the destination NAS to update packages.
• We recommend updating all packages to the latest version to ensure all services work properly, and have security fixes and new features.

3.2 Configure packages

If you have the following packages installed on your source NAS, check the configurations in each package.

• Active Backup for Business: If you have previously used this package to backup a virtual machine, launch Active Backup for Business, go to Virtual Machine > Manage VMware vSphere > Edit, and re-enter VMware vSphere's credentials.
• Central Management System:
  • If the source NAS was a CMS host, disable the Central Management System package on the source NAS to ensure there's always one running CMS host only. However, DO NOT uninstall the Central Management System package on the source NAS. Otherwise, all of the managed server will be removed from CMS host.
  • If the source NAS was added to a CMS host as a managed server, go to Central Management System > Server on the CMS host, select the source NAS from the server list, and click Remove. Then click Add to add the destination NAS to the server list.⁵
• MailPlus Server:
  1. Buy licenses for the destination NAS.
  2. Since MailPlus Server is tied to network interface, make sure the correct network interface is selected in MailPlus.
  3. If the MailPlus Server on the source NAS was set up as part of a cluster, you can re-configure it.
• Synology Directory Server:
  • Make sure to upgrade the package from Active Directory Server to Synology Directory Server.
  • Make sure to change the server name of the destination NAS to that of the source NAS. We recommend changing the server name after you have configured all package settings. For steps on how to do so, refer to Section 4.

4. Redirect external connections from the source NAS to the destination

To transfer all services from the source NAS to the destination NAS, you must redirect all external connections that are used for providing services from the source to the destination. The best way to redirect the connection is to change the server name, IP address, QuickConnect, and DDNS on the source to the destination directly. This action ensures all services can work properly on the destination NAS and prevent any abnormalities.

• Server name:
  1. Go to Control Panel > Network > General on the destination NAS.¹²
  2. Enter the same server name used on the source NAS.
• IP address: Change the IP address of the destination NAS to the source's, while selecting the IP address on the source NAS to Get network configuration automatically (DHCP) or changing it to a different one.
• QuickConnect:
  1. Go to Control Panel > QuickConnect on the destination NAS.
  2. Tick Enable QuickConnect.
  3. Use the same Synology Account to sign in to the destination NAS as the one you used on the source NAS.¹³
• DDNS:
  1. Go to Control Panel > External Access > DDNS on the destination NAS.
  2. Select the Hostname and click Edit.
  3. Tick Enable DDNS support. If your DDNS supplier is Synology, use the same Synology Account to sign in to the destination NAS as the one you used on the source NAS.

5. Shut down the source NAS

After performing the above steps and ensuring that all services run properly on the destination NAS, you can shut down the source NAS and start using your new NAS.
