Hi - as several of you know, I administer a small network of mixed Windows and Macs for my company, and I just wanted to check and see if there are any surprises awaiting my plan to swap hard drives between a new and slightly older machine. I've got a two-year old Dell Dimension 4600 (P4 1.6Ghz) that's configured with a ton of financial software that's a giant pain to install. It's running XPproSP2, and other than the finance software, it's a stock machine. New machine is a Dell 9150 Pentium 820 (dual core 2.8GHz) Rather than re-installing and moving apps, files, etc., I'd like to just grab the hard drive out of the old machine, slap it into the new, and go forward. Hard drives are same type and use the same connectors, but I'm a bit concerned about Windows/Office validation, and other machine-specific items - anything I should watch out for? I'd do this with a Mac in a heartbeat, as I've done it many times before, but never made the attempt with a Windows machine... where all kinds of basic things that should work... don't.
