I am a tester and would like some information on SAP Upgrade. I have been assigned to a project but have not had any experience on SAP. I do not know what versions they are upgrading from and to. What is involved in any SAP upgrade? What is involved in Regression testing the SAP application?
You will need to refer to your SAP documentation for upgrade information. This forum does not supply information, nor should be expected to supply information about SAP. Regression testing for an upgrade should be no different than general regression testing practices for anything else.
