Database refresh on quality system.

Dear Experts,

We need to refresh PRODUCTION system ERP 6.0 EHP5 to existing QUALITY system. We have gone through below thread https://forums.sdn.sap.com/thread.jspa?forumID=186&threadID=213898 but bit confused about procedure. Is it ok to go with this thread?

Remote client copy is not feasible in our case also it will take days to complete

Kindly let us know steps/ procedure for refreshing database.

Your help would be appreciated.

Thanks and Regards,
