I wouldn't recommend cloning from hdd to ssd. It's a lot of work and still could have troubles. Aligniment and the native adjustments 7 does w/clean install won't happen. Depending on where you are and what you can get 7(I presume)for, it would be worth the extra $ to clean install to the ssd. I've bought new sealed 7 Ulti. retail 3 times in the last 8 mo. from private parties for $70 each time.
Back up the hdd and format it as storage.
