SAP PI to PO Migration Checklist

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
  - XI -> SOAP (XI 3.0)
  - HTTP -> HTTP_AAE
  - WS -> WS_AAE
- RFC Destinations
  - Use Destinations in NWA to create HTTP and RFC connections to backends
Mapping
- No more use of ABAP/ABAP-XSLT: Redesign in Java!
- Keep on using Swing Client! NWDS/Eclipse is not comfortable enough…
Routing
- Classic Routing -> Integrated Configuration (ICO)
  - Make sure you understand the settings for Staging & Logging!
- Multi-Adapter Engine Usage (ICO-ICO)
- Usage of iFlows & Folders in NWDS/Eclipse (optional, but recommended)
BPM
- Redesign ccBPMs: replace BPM by Adapter Modules (e.g. Async-Sync Bridge) or Collect BPMs
- Create BPM processes to replace ccBPM
Basis
- CTS+ now e.g. via ABAP Stack of SAP Solution Manager
- User Management now locally (UME) or connected to Active Directory
- Set up NWDI for BPM Design Time Repository & Transport
Monitoring
- No more SXMB_MONI
- All messages are visible in PIMON
Alerting
- New Message based alerting available, configured in DIR/NWA
Backend Systems (SAP ECC/ERP, CRM, SRM, …)
- IDoc – WE21: New IDoc Port to connect with IDoc_AAE via RFC Destination type T (SAP Gateway)
- ABAP Proxy – SXMB_ADM: Point to Adapter Engine RFC Destination instead to Integration Engine (configured globally or per outbound Service Interface/Proxy)
