It sounds like your best bet is to just import user data and such, and then reinstall applications as wanted.Thanks for the advice about settings.
Another question: The old iMac has Parallels installed along with Windows. She doesn't want either on the new iMac. Is there an easy way to stop these applications from moving to the new iMac while allowing other applications to migrate?
Migration Assistant will work fine from SL to ML. Just delete the Parallels VM from the old machine before you do the migration. You might want to give this a look also.My wife just got a new 2012 iMac with Mountain Lion. For setup, will the migration assistant work with her old iMac running Snow Leopard?
