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.

    I am attempting the same thing but am having an issue where it is telling me the Nic Teaming (LBFO) needs to be removed. I have attempted the below powershell command but still get error when attempting upgrade with keeping files and apps.

    PS C:\> Get-NetLbfoTeam | Remove-NetLbfoTeam
