Narrative:
While in cruise at FL280, ZLA issued a clearance to FL290. Captain acknowledged the clearance and we confirmed the new altitude with each other. I began a climb in vertical speed (1000 FPM) and passing FL282 got a TA on an aircraft at 7 NM which quickly transitioned to an RA on the same aircraft at 5 NM as I passed FL284. I immediately responded by disconnecting the autoplt and autothrottle and descended back towards FL280 -- closest approach to the other aircraft was equal/greater than 500 ft separation on TCASII. We were just about to advise ZLA of the incident when the controller advised us to maintain FL280.

Title: AN MD80 FLT CREW RECEIVES A TCASII RA AFTER BEING CLRED TO FL290 WHERE THE OTHER ACFT WAS.
Narrative: WHILE IN CRUISE AT FL280, ZLA ISSUED A CLRNC TO FL290. CAPT ACKNOWLEDGED THE CLRNC AND WE CONFIRMED THE NEW ALT WITH EACH OTHER. I BEGAN A CLB IN VERT SPD (1000 FPM) AND PASSING FL282 GOT A TA ON AN ACFT AT 7 NM WHICH QUICKLY TRANSITIONED TO AN RA ON THE SAME ACFT AT 5 NM AS I PASSED FL284. I IMMEDIATELY RESPONDED BY DISCONNECTING THE AUTOPLT AND AUTOTHROTTLE AND DSNDED BACK TOWARDS FL280 -- CLOSEST APCH TO THE OTHER ACFT WAS EQUAL/GREATER THAN 500 FT SEPARATION ON TCASII. WE WERE JUST ABOUT TO ADVISE ZLA OF THE INCIDENT WHEN THE CTLR ADVISED US TO MAINTAIN FL280.
