Ok !
That's the logical step you were making and that was in your mind, but that wasn't in mine (and maybe not in other readers' either) :
- Migration Assistant "cleans up" things, since it's only copying the needed stuff
So it's recommended to use it for a new main computer.
- SuperDuper will copy every bit of information so there's no need to clean first.
That's perfectly logical.
Thanks for clearing up my mind too
