You'd need a fresh install, since the hardware would be very different. I wouldn't recommend even trying, as I've seen folks do similar things with in theory identical hardware and the drive wouldn't boot on the new, and not on the old when moved back.
These both make me so happy to read....
Has anyone tried the "multiple houses" I've heard about? I've only got the original and don't want to buy one just to test it out...
