The BBs are different but the frames are the same. The BB30 is a different frame design, but you don't have one of those so no worries. The FSA crankset and BB should swap onto the older frame. If you run into bearing adjustement issues you might need to have the old frame's BB shell faced (cleaned up) as I've heard the new external BBs can be quite finicky.
