My new hexacorer arrives tomorrow and am making plans for the switch. I originally I assumed I could remove my SSD from my current machine and just pop it in, but I reslized today that the 10.6.4 build is different than the current one that Apple has seeded to the community. Am I wrong that this wouldn't work? I'd rather avoid losing a lot of my settings that I've had for over a year, unless it will be better in the long run. I have never used migration assistant and have my doubts about it's effectiveness . . . but wanted to know what most of you guys did when the new machine arrived. Start fresh, time machine restore, superduper, migration assistant or any other methods?
