Service Pack Upgrade.

Hi,

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.

CURRENT REQUIRED

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.

Regards,

Murali Mani.
