Please note that this is a technical forum, and not a place where you can get authoritative answers on legal matters. To that end, you need to talk to your local Microsoft representative or call a Microsoft Licensing Specialist, 1-800-426-9400), Monday through Friday, 6:00 AM to 6:00 PM PST..
That said, I think it should be possible to move the license, but since the conditions are not exactly the same with physical machines as with virtual machines, you may want to check the licensing guide. Or talk with Microsoft.
