In our assignment we are planning to upgrade the service packs as per the levels mentioned below.
Currently we are in SAP R/3 4.6C, we are upgrading these service packs to make the system compatible for integration with SAP GTS.
SAP_BASIS 45 54
SAP_ABA 45 54
SAP_APPL 45 50.
I would like to know what kind of Impact analysis has to be made before updating the service packs in the existing system as the present system has numerous Z functionalities.
What kind of testing has to be carried out after updation and also migration strategy from DEV to QA to PRD.
