Can you perform an in-place operating system upgrade of an actual Virtual Machine (that is living on a host Hyper-V 2012 R2 Datacenter box) from Server 2008 R2 Enterprise to Server 2012 Datacenter? Everything I find online is how to upgrade the actual Physical Hyper-V host server from 2008 to 2012, but I already have a 2012 Host server that I've migrated the VMs to (they originally lived on a 2008 R2 Enterprise Host server) and just want the VMs now upgraded from 2008 to 2012.
Any help you can provide with how to perform this task (or if it's even supported) would be most appreciated! If supported, it should be as simple as mounting the .ISO into the VM and performing the upgrade, but I didn't know if the new .VHDX format of Server 2012 VMs would be an issue given these 2008 VMs currently run via .VHD files. I also didn't know if any of the Gen 1/Gen 2 settings could become a mess (clearly these are Gen 1 now).
Thanks in advance!
