The Virtual PC Guy has posted some rough notes on how to upgrade from Windows 2008 (RTM) Hyper-V (RTM) to Windows Server 2008 R2 (Beta) Hyper-V. Some things to remember:
- Only upgrades from Windows 2008 RTM and Hyper-V RTM are supported.
- You can do an in-place upgrade of W2008 with Hyper-V enabled to W2008 R2. Remember that MS prefers if you don’t do in-place upgrades.
- You can export a VM and import it.
- You can back up a VM and restore it.
- Migration of machines with saved states is not supported. Shut the VM down to migrate it.
Nothing has officially been published yet. I’m looking forward to see what the process is going to be to get from a cluster full of dedicated LUN’s to a cluster with possibly only one cluster file system.
