HI Satish
From my experience new installation of SAP system is slight easy, at same time existing SAP system migration and upgrade are major one. In your case you have to follow the steps which I already provided my early communications. or you can check with any ABAPer or Function consultant to find any other way. or raise the SAP Support ticket about your requirement.
You can check the SAP Note 1388258 along with PDF, details of SAP version interoperability of SAP Business Suite
