SAP PI/PO Migration to SAP Integration Suite
Maintenance for SAP Process Integration and SAP Process Orchestration ends in 2027. Anyone still running productive interfaces on PI or PO has a project with a fixed deadline. We guide that migration to SAP Integration Suite, from taking stock to switching the last interface off.
Assessment first, decisions second
Every migration starts with an inventory that is usually larger than expected: interfaces nobody owns any more, mappings that exist twice, and scenarios that have not carried a message in years. Retiring those is the cheapest part of the whole programme, and it only happens if someone counts them first.
Brownfield or greenfield
A like-for-like move keeps the existing logic and shortens the project, but it carries old design decisions into a new platform. A redesign costs more up front and pays back in maintainability. The honest answer is usually a split: mechanical scenarios move as they are, business-critical ones get redesigned.
That split is a decision to make deliberately, per interface, with the cost of each option on the table. It is not a decision to make once for the whole landscape.
The 2027 deadline is a capacity problem
The date itself is not the risk. The risk is that everyone in the market moves in the same eighteen months, and experienced integration people are scarce well before the deadline. Starting the assessment early costs little and keeps the options open.
Frequently Asked Questions
What exactly happens in 2027?
Mainstream maintenance for SAP Process Integration and SAP Process Orchestration ends. Systems keep running, but without regular corrections and security fixes, which is what makes it a compliance question rather than a technical one for most organisations.
Can we migrate interface by interface?
Yes, and that is the usual approach. Both platforms run in parallel while scenarios move in waves, typically grouped by business area or by partner. What needs planning is the interim period: which platform is authoritative for a given flow while both are live.
Do existing mappings carry over?
Partly. Message mappings along standard patterns can often be reused with adjustments. Custom Java mappings, adapter modules and anything relying on the PI runtime generally need rebuilding, because the execution model on Integration Suite is different.
How long does a migration take?
It scales with the number of interfaces, not the size of the company. A landscape with a few dozen scenarios is a matter of months, several hundred is a programme spanning more than a year. The assessment gives you a defensible number before you commit budget.
