Hi Anoop,
I think the best option here is to forward the request to PRD system from QAS as suggested by
Go to import queue of QAS tcode stms_import and select a TR or block of TR's and choose from Menu bar Request --> Forward --> System and give PRD SID.
In this way the TR's will appear in import queue of PRD and import them as they were imported in QAS.
You can also try to re-import TR in QAS and they will automatically appear in PRD but this is again not required.
Regards,
Prithviraj.
