I'm using SCCM to upgrade Windows OS from Windows 10 1906 to 2004. I followed the steps in this document: https://docs.microsoft.com/en-us/windows/deployment/deploy-windows-cm/upgrade-to-windows-10-with-configuraton-manager, some device upgrade successful, but some others not. They are stucking in Windows Upgrade progress: 44%
I cannot find the casue, can anyone help here? Much appreciate!
