Hi,
As indicated in the note http://service.sap.com/sap/support/notes/552711
- 4. Can I copy between systems with different R/3 releases/add-ons?
Notes 19574 and 24853 provide basic information on this subject. The main or Basis release must always be identical. Support Packages and ADD-ONS should also have the same status in both systems. Only then can the consistency of the data be guaranteed.
Also please check the note http://service.sap.com/sap/support/notes/557132 to clarify how Remote Client Copy works.
Best Regards,
Aleh
