Upgrade Hyper-v server to Windows Server 2022

Hi
I have a couple of Windows Servers that are running Hyper-V hosts on physical machines. I want to upgrade the Hyper-V host to Windows Server 2022. Some are running Windows Server 2012 R2 and some are running Windows Server 2019. My plan was to backup the specific server, then shutting down the running VMs, then running Windows Server 2022 upgrade then restart the VM. Do you foresee any problems? Can Windows Server 2012 R2 upgrade directly to Windows Server 2022 or do I need to upgrade over Windows Server 2016/2019?

Kind regards,
Kristian

    General rule is skip one version.
    https://learn.microsoft.com/en-us/windows-server/upgrade/upgrade-overview#which-version-of-windows-server-should-i-upgrade-to

    The much cleaner / safer method is to export copy off the virtual machines, clean install the operating system, patch fully, add hyper-v role, import virtual machines.

    Hi
    I did the upgrade from Windows Server 2012 R2 to 2022, and from 2019 to 2022, where it worked out just fine on all our hyper-v servers.

    I am in the same situation - all three of my Hyper V hosts are running Windows Server 2012 R2 and I want to update them to Server 2022. There are some benefits to doing a clean install however we aren't looking to do that.

    Similar to @LangeMuller question - does anyone know if there are any known problems that can can be caused. I'm looking to probably update to 2016 / 2019 first
