Hi Ashu,
I think you would have searched the SDN. This is one of them
Following tasks are to be performed while upgrading:
1. Technical Upgrade
- Version upgrade, without functional enhancements
- ABAP Code fixes
- Fixing SPDD
- Fixing SPAU
- Stabilizing the standard SAP transactions.
- Implementing known OSS Notes.
- Identify and correct the clone programs.
- Identify and correct the customer objects.
- Unit testing of upgraded objects.
- Clean obsolete objects
- Functional configuration changes (Must haves)
- Functional process testing
- Mock/Timing upgrade on production like environment
2. Functional Upgrade
- Technical upgrade + Deploying new functionalities available in upgrade version
- Package enabled Business process Re-engineering - If applicable
- Optimization of Custom objects & programs, by utilizing new functionality.
3. Unicode Conversion
- Mandatory for systems on MDMP code page, as SAP does not support these pages.
- Simple way to check if a Unicode conversion is required is to look into the number of entries in table TCPDB. More than one entry in this table mandates the Unicode Conversion.
Hope this helps you.
