Windows 10: In place upgrade of Windows Server 2016 to 2019 on a laptop fails during SET_PRODUCT_KEY

I have an older laptop serving as the primary domain controller.I am trying to perform an in-place upgrade from 2016 to 2019The install almost fully completes, then rolls back and the error message says it cant set the product keyI suspected I know why - this laptop originally came with a Windows Home licenseWhen I installed Server 2016 on it, I had to use the workaround of putting the key in the PID.txt file in the sources directorySo I did that, and retried the upgrade executing from the USB stick in the serverSame resultIs the in place upgrade not going to work?I hate having to

:)

Activate RDS CAL 2019 on Windows Server 2016

Dear Microsoft Support,



We recently purchased Windows Server RDS CAL 2019.

When we tried to install Windows Server RDS CAL 2019 into Windows Server 2016, it shows the license is not recognized and couldn’t install.



My questions are :

1. Can’t Windows RDS CAL 2019 be installed in Windows Server 2016? If can, how?
2. Is there any way to downgrade RDS CAL from 2019 to 2016 version?

Thanks,

 

Can't perform in-place upgrade from Windows Server 2016 to Windows Server 2019

When I run the Windows Server 2019 installer to upgrade from Windows Server 2019, the option for an in-place upgrade is greyed out. How can I perform an in-place upgrade?

When I use this: dism /online /get-targeteditions

I get this: (The current edition cannot be upgraded to any target editions).

DISM says my current edition is ServerDatacenter.
