How to fix permissions issue from a file server migration between 2 domains?

I have a file server migration project that is currently giving me some permissions issues. This is between 2 different domains(Lets call them Alpha and Beta domain), they both have validated trusts between each other and are on the same network. I have tried two different routes to migrate the data, one using a 3rd party app (SyncbackPro) that copies all existing permissions from the original server (Windows 2016 Standard) on Alpha domain to the new server (Windows 2019 Standard) on Beta domain. The second method using a cloud backup service to just restore the folders/files with original permissions intact to the new server on Beta domain.

Both routes mostly transfer the data successfully over with some errors that usually occur about 6+ hours in, which my guess is just because of the sheer amount of files, the transfer service crashes but i think that is a separate issue. I manually have checked the security permissions on the folders, all permissions that should be there, do show up.

The main issue now is all the migrated files on the new server in Beta domain, it seems we somehow lose all admin rights to the folders even though the security settings show we have them. Every time I try to open, move, or even delete the folders I get an error "You require permissions from Administrators to make changes to this folder", even though I have tried this while logged in as a domain admin or a local admin. When i try to manually re-add full control on the folders to the admin groups i get "Failed to enumerate objects in the container. Access is denied." I have tried completely turning off UAC, running explorer.exe as an admin, and changing the folder owner(which it will not let me, gives me the same error message).

Any insight or ideas to troubleshoot this issue would be greatly appreciated!!

    Hi,

    Thank you for posting in Microsoft Q&A forum.

    It seems the problem is NOT a MCM related problem. To get accurate help, it is suggested to try to contact Active Directory support. Here is the support link:

    Thanks for your time. Have a nice day!

    Best regards,

    Simon
