I seek for your advice on Test approach for SAP Upgrade from EHP 5 to EHP 7
I do release management but I have never been responsible for test management on that kind of project.
We are going to start upgrade from sandbox, than test tier and go-live is schedulled in few months.
What kind of level of testing is advisable? is Unit, UAT and Regression enought? would you focuse on Risk Based Testing approach? or would you test everything there? Is sandbox right tier for regression testing? or other functional testing is recommended? Is integration testing usually preformed in sandbox?
If there are any materials or simillar discussion on SCN please point me in right direction.
From last upgrade (offshored) I have recieved information that end-to-end processes needs to be tested but for me it is deffinetly to little information.
Thank you in advance!
