I have a few questions regarding upgrade with respect to SAP Security.
1) How to find the New Transaction codes that SAP has introduced and Tcodes that have been considered obselete by SAP , if im upgrading from 4.6C to ECC 6.0?
2) I heard that SU25 utility is not the widely used tool to find the GAP between two Versions of SAP. If this is right, please let me know the drawbacks or disadvantages of running this tool.
Any help on this will be appreciated.
