PI TO PO MIGRATION

We cannot upgrade from dual stack PI to single stack PO.

All integration content has to be moved/redesigned and tested

• 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)

Area	Activity	Objects
SLD	In case you are using a central SLD, point your PO system there. Otherwise you Export/Import	> Software Products > Software Components > Technical Systems > Business Systems
ESR	Export/Import via TPZ all relevant objects. Decide which source system to use (DEV/QAS/PROD)	> Software Components
DIR	Migrate all Channels & Routings using the tool where possible	> Communication Channels > Business Components > Routing Objects
NWA	(Re-)define the relevant objects in NetWeaver Administrator	> Keystore > Destinations > User Management > Alert Configuration

INT4 & FIGAF can be used for automated testing of interfaces.
