Upgrading Hyper-V 2012 R2 (Stand-alone) to Windows Server 2012 R2 Standard GUI

    Question

  • Hi Experts,

    I am looking forward to upgrade my Hyper-V 2012 R2 to Windows Server 2012 R2. As per my knowledge, we cannot upgrade Hyper-V Stand-alone offering to Windows Server. I am considering different approaches and have no issues bearing downtime. But any approach having zero noticeable downtime will be appreciated too.

    I am thinking of different approaches

    Approach 1: Live Migrate VMs from one host to Another. Do a clean install of Windows Server 2012 R2 Standard with GUI on Hyper-V Server Physical Host. Migrate back the VMs to the original Host.

    Approach 2: Export VMs on another Partition of the Same Host. Example D: Drive. And then do a clean install of Windows Server 2012 R2 on that host. Turn on the New VMs with existing VHDs

    Approach 3: Export VMs to an External Disk. Do a clean install of windows server 2012 R2 on that host. Turn on the new VMs with existing VHDs.

    My Questions:

    Q1: Do we have any better approach approach than the above mentioned?

    Q2: Is any of these approaches is 'not recommended'? Are there any challenges?

    Q3: What is the best scenario among Approach 2 and 3 if I don't have any other physical host other than the one I am migrating from.

    Any kind of help will be appreciated. Documentations, best practices or any kind of Architectural details would help. 

    Thanks

  • Hi,

    Q1: I suppose approach one is the best.

    Q2: Approach 2 and 3 are similar, they are easy to operate but would cause some downtime.

    Q3: For the safety of the VM data, you could export VMs to both another partition and external disk.

    Best Regards,
