I am retiring a Windows 2003 R2 member server that currrently hosts Virtual PC 2007 and a dozen virtual machines running Windows XP Pro. The new Server is running Windows Server 2008 R2 Standard. Is Virtual PC 2007 and its VHDs compatible with WIN2K8 R2? If not, what do the Experts recommend? The problem is that I have to complete this project today, Sunday, 10/02/2011.
