Narrative:

I was working 'left' scope (fll departure radar). A BE20 departed and reported 060 degree heading, climbing to 2000 ft. I said radar contact, climbed him to 5000 ft and issued left turn to 360 degree heading. C525 being worked by 'right' (fll arrival radar) was being vectored around fll for a landing at opf. He was at 6000 ft. I asked BE20 for his altitude. He stated, '6400 ft for FL290.' they passed within 1 mi and a few hundred ft (exact ft not known).
