Yes. I studied for the 7 for 2 weeks solid and took it on a Tuesday, then registered for the 63 that Thursday and took Wed off to study. There is no direct overlap per se, except in some options type stuff, but I can recall thinking on a number of topics that they would be more difficult for someone who was neither experienced in Finance nor in the CFA program. If you passed level I, you should knock it out easily, but you do need to put in the time because there is regulatory stuff involved that might not be familiar or common sense.
