Narrative:

Departure cleared other aircraft to descend below us after that aircraft reported us in sight with the comment that they would give ATC a good descent rate. Then ATC cleared us to climb after we reported other aircraft in sight. I responded to TCASII RA, disconnected autoplt and increased climb rate to avoid other aircraft. ATC mentioned that aircraft merged on her screen.
