Windows 10: windows server 2012/16/19 upgrade

Hi all , I am facing troubles while doing the upgrade from windows server 2016 Evaluation standard to Windows server 2019 Evaluation Standard . I can do a clean upgrade ,wiping out the personal files and apps , but I need to keep those files and apps . However I can't choose the second option . Only erasing all file is available . Same thing happens when I try to do upgrade from Windows server 2012 R2 to server 2016 or 2019 !! What might be the problem ? Do I have to get a full licensed windows to be able to do such upgrade !Any help or a hints are appreciated . Thank you in advance

:)

IF you want to try seizing the FSMO roles to see if it will help, here is a quick guide (this should be done on the DC you want to keep):

Knowing that this is a DC now I'm really convinced that something is wrong with the AD account for this particular server. It's possible that the promotion to a DC didn't work correctly leaving you with a sort of broken DC.

A reboot is always worth a shot; has that been tried Ahhzz? If it has, then the next step would be to demote this DC and rejoin it to the domain. Once rejoined you can run DCPromo again. Microsoft best practice is to have at least 2 DCs for redundancy.

Also don't forget to reset the account in AD Users and Computers to avoid any SID issues.
