Hyper-V host missing supported version 9.0

Hello everyone...

I have two servers, both running Windows 2019. One both servers I run the command "Get-VMHostSupportedVersion", but the results are different.

On server #1, I see this:

On Server #2, I see this:

As you can see, I am missing version 9.0 on one of them, and that is preventing me from doing a migration from one server to the other.

I'm a little baffled, because both servers show they are fully up-to-date as far as updates go. The server that was missing version 9 is much newer than the other server; so maybe a hotfix was released in the past that the new server didn't get to see.

Does anyone know how I can get version 9.0 going on the Hyper-V host?

    Thank you for your snapshots! The information displayed indicates that the highest VM configuration versions of your two Windows 2019 servers are 8.0 and 9.0 respectively. So I suppose that the versions of your two servers are different, although their editions are the same, and that can be the reason why your 9.0 version was “gone”.

    I suggest you firstly to follow the guidance in the document below to check the true versions of your two servers respectively:

    You may get the information like this:

    In your place, your two servers have the same edition: Windows 2019 while their versions may be different.

    I suggest you to check the VM configuration versions that your two servers support respectively. If the server version is too low to operate your migration, you may have to update to the appropriate server version. The information about the supported VM configuration versions for long-term servicing hosts can be seen from:

    Thank you for your time! If you have any other concerns please feel free to feedback!

    Best regards
