I have to admit that I find this KB article and support statement to be quite baffling.  It states that:

Moving a virtual machine (VM) from a Windows Server 2012 R2 Hyper-V host to a Windows Server 2012 Hyper-V host is not a supported scenario under any circumstances. 
When you try import a VM that is exported from a Windows Server 2012 R2 Hyper-V host into a Windows Server 2012 Hyper-V host, you receive the following error message: 

Hyper-V did not find virtual machines to import from the location <folder location>.
The operation failed with error code ’32784′.

I am going to raise this with the product group. I see it as a genuine issue because anyone doing an upgrade-migration will require a rollback plan that will work and is supported.

You can move a VM from a Windows Server 2012 Hyper-V host to a Windows Server 2012 R2 Hyper-V host. This is a supported scenario and cane even be done with zero downtime using Cross-Version Live Migration.

  1. Replica does not work either between 2012 and 2012 R2 which creates and awkward upgrade path where you break a redundancy scenario.

  2. Hi Aidan, Did you get any useful feedback from MS on this? It’s putting me off trying R2 if there might be issues if I need to roll back. Thanks!

    • Nope.

  3. this is bummer..
    why it isn’t supported…
    I need to go back from Win2012 R2 to Win2012….
    any way around this?

  4. do you have any answer from ms?

  5. Any info, this is a huge pain in the ass trying to roll back….

  6. Old thread but just re-create the VM on the new server and attach the disks.

    Easy peasy :)
