Any major changes to Migration Assistant in Mountain Lion? All I want is the ability to move over iPhoto, iTunes, Contacts, and iCal data without moving anything else associated with "user". A lot of cruft has built up in my Library folder and elsewhere. I want to start over with a clean install to remove all the build up but moving the above items manually is a royal pain. It'd be great if you could be a little more specific about what Migration Assistant is allowed to migrate.
