Hyper-V virtual machine versions after host OS upgrade from Server 2012R2 to 2019 RRS feed

  • Question

  • Hi

    Looking for advice on how virtual machine versions are handled during a host upgrade from Windows Server 2012r2 to Server 2019. The setup is as follows:

    Production Site - 2 x Windows Server 2012 R2 hosts with Hyper-V Cluster

    DR Site - 1 x Windows Server 2012 R2 host with Hyper-V configured as replica server.

    The customer wish to upgrade the the 2 production hosts from Server 2012R2 to 2019 but leave the DR replica server running on Server 2012R2.

    When upgrading the OS to 2019, will the virtual machine versions stay at 5.0 or are they automatically upgraded? Need confirmation on this as if the versions are auto upgraded then the OS would also need upgraded to 2019 to ensure the virtual machines versions are the same.

    Thanks in advance

  • Hi,

    The virtual machine versions will stay, they won't be automatically upgraded, do note that you won't be able to use  some of the new virtual machine features until you manually update the configuration version.

    If you export a virtual machine, it retains its configuration version.
    The import process on Windows Server 2016/ Windows Server 2019 does not upgrade version 5.0 virtual machines, they will remain at version 5.0 until you deliberately upgrade them.

    You'll find more information about the Hyper-V configuration versions over here:

    Best regards,

  • Thank you for confirming. If i remember correctly if you upgraded from 2008R2 to 2012 then this would auto upgrade the virtual machine versions.
