Hyper-V 2012 R2 "in-place upgrade" export config only ?

Hello,

I do have a single server acting as Hyper-V host and running 3 productions VMs (SBS 2011, TS 2008 R2 and Linux PBX) and several test VMs. The host is currently running Windows 2008 R2 Enterprise and I plan to upgrade it to Windows 2012 R2 that has RTM'd yesterday.

Win2008 R2 Boot partition (C:) is a RAID1 partition. This is the one I want to upgrade.

Productions VM are located on separate RAID volumes. Tests VM are located on a QNAP appliance and are mounted through iSCSI.

My approach would be to:

1. Shut VMs down
2. Export Config using the scripts documented at http://blogs.technet.com/b/virtualization/archive/2009/05/29/hyper-v-r2-import-export-part-6-so-what-happened-to-configuration-only-export.aspx
3. Perform  a clean install of Windows 2012 R2 and configure Hyper-V
4. Import the configurations using the VBS scripts mentionned here above

My question is two-fold:

1. Does anyone know if the Import Config script will run with Windows 2012 _R2_ ?
2. Is there a better approach ?

Thanks.

I would export all virtual machines (full, not the config only) for backup purposes and then upgrade the host.

In-place upgrade of Hyper-V is possible. However, you need to make sure that all virtual machines are without snapshots.

I don't have enough disk space left to export the VMs. However, I do have backups of all VMs.

The Windows 2012 R2 Hyper-V import wizard allowed me to import my existing VMs. I just had to make sure that all VM related settings where stored on a partition unaffected by the removal of Windows 2008 R2 and the installation of Windows 2012 R2

I did not find any info about the ability to run the mentionned scripts with 2012R2. I found an alternative solution by running the built-in import wizard.
