There is no upgrade path from dualstack SAP PI to singlestack SAP PO. All integration content has to be moved/redesigned and tested.
This is a list of activities which might impact you partly or even completely.
- Connectivity
- Communication Channels (Replace all ABAP adapters with JAVA adapters)
- IDoc -> IDoc_AAE

- WS -> WS_AAE
- RFC Destinations
- Use Destinations in NWA to create HTTP and RFC connections to backends
