Better to migrate before upgrade to Lion, or upgrade before migrating? I'm getting a new MacBook Pro, and I am wondering about the relative merits of:


installing Mountain Lion on the new laptop before migrating my account from my old MBP; or
migrating my account and then upgrading to Mountain Lion


Or are the two methods functionally equivalent?
It is best to upgrade and then migrate. Usually problems occur while upgrading, and it is best to upgrade or install from scratch, as opposed to upgrade on a system which might have something incompatible already installed.
