we've got an SAP PI dual stack installation 7.31, with many ccBPMs. In order to minimize risk we are planning to do an upgrade to 7.5 with split.
After we are planning to move ccBPM to AEX (BPM), in 2021. After all ccBPM are migrated, we don't need ABAP stack anymore, so how can we "uninstall" ABAP system? Is there any restriction? Is there a guide for uninstallation of ABAP stack on a split installation of PI?
