I have a 2010 Mac Pro. Still running Snow Leo, as there are still quite a few programs that are PPC and I'm not prepared to update all of them.
My current boot drive is 1.5TB and I'd like to swap it out for a new 3TB. From past history I'm looking between the Apple Migration tool and Carbon Copy Cloner.
The migration tool will mean a full install to the new drive, and then migrating, while CCC just a full copy. Seems the migration might be more effort but might help leave some garbage behind. The current system has been slowing down, and I'd imagine a new OS install would help get it back to the "new Mac" speed.
Any thoughts on these two methods and my goal? i.e. a speedy-fresh install with all my software moved from the older drive.
