In our landscape, Enterprise Portal connected with R3 4.6. There are couple of custom WebDynpro applications developed on NWDI track by using Z RFCs in R3 4.6
Now client planning to setup a new ECC 6.0 system which will maintain all Z RFCs from R3 4.6 and planning to add few fields in Z RFCs. Going forward they will decommission R3 4.6 system and Enterprise portal will connect to ECC 6.0.
As current applications pointing to R3 4.6, what are the steps I need to take to work these applications error free as part of system change.
My questions are -
1. Do we need to reimport models. If so, do we need to do remapping for entire application?
2. About JCos
3. Need to create system object in portal?
I request, please let me know the check list to perform from portal front end.
Appreciate your valuable suggestions.
