Client Export /Import from one SAP Environment to Another SAP environment

Hi Expert,

We are in process to client export/Import one SAP Environment to Another SAP Environment only client dependent data. I have done Client Export from Source client and get two file KT* KX file which is client Dependent.

I copied both the file and past in target system DATA File and CO FILE folder. After that I added both the request in the TMS of target system. And then started t KT* Request Import. Request imported with return code 8.

I start post import step, Run SCC7. But after ten minutes this will also terminated.

So my question is that the post import process (SCC7) is terminated due to Return code 8? Or some other reason ? or without successful request import post process is not complete ?

If someone have good information please help us.

Please share your views. Thanks in advance.

Regards
