We are preparing to replace a 2008R2 Hyper-V cluster with a 2012 Hyper-v cluster.
We were thinking that we would come in on a weekend. shutdown the 2008R2 boxes, move the San connection to the 2012 boxes and configure the cluster. All of the VM files would be on the SAN then we would use import-vm to just import all of them.
We setup a test lab with the 2012 server cluster on a small SAN for testing. We copied a few of the VM directories over to the lab system.
What we have found is that we can use the wizard to import the VMs with no problem and even with snapshots.
But if we use PowerShell import-vm we get errors telling us to run compare-vm. When we run Compare-vm it tells us the problem is incompatible snapshots.
So I guess the question is: Why can the wizard do it and not the underlying powershell?
Any way around this? I really do not want to do them one at a time with the wizard.
Thanks in advance.
