I have a virtual hard disk file (VHD) created using Microsoft Virtual PC 2007. Can this file be copied to a host running Microsoft Virtual Server 2005 R2 and be used as the basis for creating a new virtual machine? Essentially, are the VHD file formats between the two products compatible, or do I need to create a new VHD from scratch? Thanks.

The VHD standard is common between Virtual PC, Virtual Server 2005, Hyper-V and even the bootload in Windows 7/2008 R2.

You will have to upgrade the VMAdditions/Integration Components (well you do if you move from Virtual Server 2005 to Hyper-V) to pickup the latest drivers, HAL, heartbeat services. In my experience it is easier to remove the VMAdditions prior to moving it to the new virtulaisation platform.

Good luck..

Thanks. I had thought that to be the case, but I wanted a 2nd opinion. – SteveM82 May 11 '10 at 15:48
