we are going to start an upgrade project of our ERP 6.0 system from EHP4 to EHP6 and I'm interested to know if I can use retrofit in order to manage in a structured way the double maintenance during the transition period of the project. My goal is to retrofit the TR created in the maintenance landscape (ERP 6.0 EHP4) to the upgraded development system (ERP 6.0 EHP6). By reading the documentation available in sdn and in the SAP help it seems that this should be feasible but I didn't find a clear statement about the feasibility of this approach. Can any one tell me if retrofit can be used in upgrade project as previously described?
thanks in advance for your collaboration.
