📎 AI Summary:
The original poster plans to upgrade a Hyper-V cluster from Windows Server 2016 to 2022 by replacing servers one at a time and rejoining them to the cluster, which will temporarily contain a mix of 2016 and 2022 nodes. They inquire whether virtual machines can be migrated between different versions during this process, to which the reply confirms compatibility, provided the cluster functional level is updated to 2022. The overall sentiment is positive and informative, with community members emphasizing the importance of backing up system settings.

I have a 3 server Hyper-V cluster running on windows 2016. I want to upgrade all the 2016 servers to 2022 servers, and I want to perform clean installs.

I will remove 1 server from the cluster, format it, install windows server 2022+Hyper-V and join it back into the cluster. (theoretically, I will repeat, until all servers are 2022). So at some point I will have Hyper-V 2016 and Hyper-V 2022 in the same cluster.

Will I be able to migrate machines from the servers running 2016, to the server running 2022, so I can continue with the format/upgrade/join cluster process? Are the 2 versions compatible?

Thanks

That should not be an issue. You will need to update the cluster functional level to 2022.
