Refresh a Development system from a Production system

Hi

Our developers want to refresh the Dev system by doing a copy back of the Live system. We have done this for the QA system before (database restore, change SID, post steps etc) but never for the DEV system.

I have seen thread Peservation of program history when refreshing a development system which talks about preserving the versions history (as per SAP note 130906); are there any other additional steps that need to be taken / any documentation for doing this? The R/3 system copy documentation only says: "If you have made modifications in your development system, do not copy your quality

assurance or production system onto the development system. Otherwise, all versions of

the modifications will be lost." I can't find any useful information about copying back to DEV.

Thanks
