We are currently on SRM4.0 BP(Business Package) on EP6.0 (J2EE 6.40) and backend is SRM 4.0 app server.
Now we are upgrading the Portal to EP7.0 and SRM to 5.0, and after seeing the SAP note number 836944, I came to a conclusion that SRM 4.0 BP on EP 6.0 cannont be migrated to EP7.0
But when I tested the SRM 4.0 BP content on EP7.0 with backend as SRM 5.0 server, everything looked fine (didn't test all the scenarios).
Could you anyone give me some insights on :
1. overall how to go on this approach
2. if we need to move to SRM 5.0 BP, how to undeploy the SRM 4.0 BP
3. redesign my portal content to reflect to SRM 5.0 BP
