When I eventually upgrade to Snow Leopard, I'd ideally like to do a fresh install (I did Tiger>Leopard as an upgrade install), but I really don't want to have to go through the hassle of reinstalling all my apps afterwards. So, would the following work as a best-of-both-worlds alternative? 1. Update my backup bootable system drive image on my external FW drive 2. Wipe the drive in my MBP and do a fresh install of SL 3. Use the Migration Assistant to automagically copy all my data and apps over from the backup drive as if I was upgrading from an old Mac to a new one On paper at least, it looks like it ought to "just work"... but I'm wondering whether or not Migration Assistant will work between a Mac and an external drive, or does it have to be between two actual Macs?
