Migrate/Move "Windows 2012 R2 Guest Cluster" From Windows server 2012 R2 Hyper-V to Windows Server 2016 Hyper-V

    Question

  • Hi everyone, I have just read the guide of how to upgrade a 2012 R2 Hyper-V cluster to 2016 Hyper-V cluster (https://technet.microsoft.com/en-us/windows-server-docs/failover-clustering/cluster-operating-system-rolling-upgrade).

    In this guide it says:

    The following scenario is not supported in Windows Server 2016:

    • Cluster OS Rolling Upgrade of guest clusters using virtual hard disk (.vhdx file) as shared storage

    But I don't fully understand this statement.

    Does it mean that I have to delete the VMs that compose the Guest cluster and create a new one under Windows 2016 Hyper-V?

    I suppose it has something to do with the new VHDS disks.

    Hopefully someone will be able to shine some light on this topic.

    Thanks a lot for your time,

    Ivan Mckenzie

    >>Does it mean that I have to delete the VMs that compose the Guest cluster and create a new one under Windows 2016 Hyper-V?

    This applies to a guest cluster .

    When you want to update a guest cluster (2012 R2 vm cluster ) .

    If you are going to upgrade physical 2012R2 to 2016 , just ignore this .

  • Thanks Elton for your reply.

    Just to make things clear.

    My hosts are Windows 2012 R2 Hyper-V and will be upgraded to Windows 2016 Hyper-V following the guide.

    I dont' want to upgrade my VMs, just live migrate from 2012 R2 hyper-v host towards 2016 hyper-v host.

    My guest cluster VMs (Windows 2012 R2 with shared disks) will also be live migrated towards a 2016 hyper-v host. This last point is my only doubt. But if I understand your reply correctly, this will work.

    Can you confirm please I have understood every thing correctly.

    Thanks a lot,

    Ivan Mckenzie.
