    Hi,

    Cluster nodes should have the same OS version.

    Mixed version cluster only exists in a few scenarios, such as cluster rolling upgrade. So, it's not recommended to add Windows Server 2012 server into Server 2008 R2 cluster.

    About cluster rolling upgrade:

    Thanks for your time!
    Best Regards,
    Anne
