How to Migrate or Upgrade WSUS
Before upgrade, you may need to do some preparation
Backup WSUS database and content: Make sure you have a complete backup of your WSUS database and the WSUSContent folder.
Verify server settings and document your current WSUS configuration, including product and classification selections, synchronization schedule, and approval rules.Check the health of your WSUS installation using the WSUSutil.exe tool to ensure that there are no errors in the current environment.
Compatibility Check: Ensure that your existing hardware or virtual environment meets the system requirements for Windows Server 2022.
Verify that all your downstream servers, clients, and other integrated services (like System Center Configuration Manager, if used) are compatible with a WSUS running on Windows Server 2022.
Best Regards,
Hania Lian
