Copy transport requests between clients of same system

Dear Experts,

we have created a NEWCLIENT(200) on our QAS system now we want all the requests imported from DEV  into our  OLDCLIENT(100) to be available in our NEWCLIENT(200) we have almost a  thousand requests. I tried scc1 but here it is asking for a particular request number, I want to copy whole in one run as a background job.

Kindly suggest me the reliable procedure.

Thanks In Advance.

Regards,

Domnic.
