Hi Chetan,
Please correct me if I am wrong, but I think you are looking for "Transport" mechanism and not "Migration" mechanism.
Moving objects from the Development environment to QA and Production environment can be done with the transport mechanism.
Please refer to multiple threads on this topic on this forum. One good discussion thread can be found at
http://scn.sap.com/thread/3245339
Please refer to the technical operations manual and Admin Guide which can provide you all the required information for CTS+.
As mentioned in the HANA Technical Operations Manual:
The process for transporting changes from a SAP HANA development system to a quality assurance and further on to the productive system starts in SAP HANA Studio. There you retrieve content from the HANA source system and export it to enhanced Change and Transport System (CTS+) in SAP Solution Manager. The exported delivery units are attached automatically to a transport request of CTS+. After you have released this transport request, CTS+ triggers the automatic activation of the change in the SAP HANA repository on the target system (quality assurance or production).
Hope this helps.
Regards,
Ravi
