Hi Chowdary,
This is very big topic to discuss and create a model.
But if we speak simply:
- When your Implementation project is go-live, you should close it.
- After that, create Solution if not already exist and import all business scenarios structure to that Solution.
- When Solution is ready and Maintenance project is also recomended you may use it for daily-support things.
- For Upgrade, this is depends on what type of upgrade you will do, technical and functional or just technical.
- For techincal create upgrade project export all Business structure from solution, when you do upgrade system you can use Upgrade Projcet plan structure as a Basis for you Test plan to check everything is working but this will cost people-time. So may be better only check customer things.
- For Functional and technical you may linke Upgrade roadmap prorvided by SAP here you must make a new test plan and test every scenario / transaction etc...
Please make it more clear, what do you expect from Upgrade Management in Solman.
