Issues with Windows 10 to Windows 11 Migration via WSUS

Hello,

I’m encountering an issue with the migration update from Windows 10 to Windows 11 through my WSUS server. When I attempt the update without using WSUS, it works as expected, but it fails when I try to deploy it via WSUS.

Here’s a summary of the current configuration:

  • WSUS Communication: The client machines are properly communicating with the WSUS server. Capture d'écran 2025-05-16 154319
  • Synchronization: The updates are correctly synchronized, including both the product and classification selections.

Group Policy: The GPO pointing the clients to the WSUS server is applied and functioning as intended.

  • Windows 11 Update: I’ve explicitly specified the update to Windows 11, including version 24H2. Capture d'écran 2025-05-16 154417 Update Permissions: Updates are allowed, and all necessary approvals are in place.

Despite all the configurations appearing correct, the migration process does not start via WSUS.

Has anyone experienced a similar issue, or can you suggest any troubleshooting steps I may have missed? Any help would be greatly appreciated.

Thank you in advance!

    Follow my guide - part 3, 4, 5, 6.

    It looks like you have introduced a dual scan scenario as those settings in your last screenshot are not those of WSUS, but those of WuFB.
