We are on the verge of migration of SAP PI / PO to CPI.
A major portion of our interfaces are SOAP/ REST -> PI-> PROXY.
Many blogs and articles on scn mention Odata as the mode of service to go to in S4 , we are still on ECC and will get get there soon. Meanwhile we want to finish SAP PO to CPI migration.
I have tried to use XI adapter of CPI and it works like a charm... seamless...
What I am confused about if this is the way to go ahead in S/4 too?
Any major changes/ upgrade strategy suggested by SAP as they have only external vendors/ partners providing the migration tool.
