Impacts and Challenges while migrating SAP PI 7.0 to SAP PO 7.4
We are planning to upgrade version to SAP PI 7.4 dual stack(ABAP+JAVA).
So all the interface objects and configurations etc are migrated from SAP PI 7.0 dual stack to SAP PO 7.4 dual stack.
I could like to know if there is any major impacts and challenges while migration and its importance. Please help.
