Process of moving TR from Quality to Production

Dear Experts,

we are in a process of moving TR from Quality to Production. While moving we faced transport incositencies like some old requests have been overwritten into the new one and dependant objects were failed during import in PRD. Now production rehearsal client is kind of messed up. what is the right procedure to transport the requests from Quality to Production. (actually we transferred the TR individually based on the list send by the respectivr module owners). Please help me to findout the solution for this issue.

regards,

Yasin.
