Hi,
1,What version of MECM and Windows ADK you are using? To support Windows 11 23H2 as client, we must use MECM version 2211 or later. Please refer to below guide:
https://learn.microsoft.com/en-us/mem/configmgr/core/plan-design/configs/support-for-windows-11
2, ==>However, we are encountering issues with several Windows 11 compatible devices failing during the upgrade process.
Can we successfully deploy Windows 11 23H2 to the rest devices?
3,Please help try to remove any anti-virus or any other incompatible software, then try upgrading again. The first easy troubleshooting step we can do at this point is to launch setup.exe from the hidden C:$WINDOWS.~BT directory. After going through the first screens, the setup will warn us about those incompatible apps. If we don't want to run the setup.exe, we can refer to the hidden C:$WINDOWS.~BT\Sources\Panther\CompatData[date-time].xml. We'll have a couple of Compatdata.xml files, usually, the most recent one will contain the information you need. Please check if there is a faulty application and give setup the instruction to stop.
4.Follow below steps to delete cached files, then try upgrading again:
a. Empty the SCCM Cache
b. Delete the content of C:\WINDOWS\SoftwareDistribution\Download folder
c. Delete the C:$WINDOWS.~BT folder (hidden)
d, Retry the deployment
Thanks for your time.
Best regards,
Simon
