The 'SAP 2027 deadline' is the widely-cited end of mainstream maintenance for SAP Business Suite 7 — ECC and its companion applications — with an optional extended-maintenance window beyond it. It is the industry's shorthand for the pressure driving S/4HANA adoption, rather than a product in its own right.
SAP mainstream maintenance runs until 31 December 2027 — the date from which SAP ceases routine corrections, security notes and legal/regulatory updates for the release. For customers who opt in, a paid extended-maintenance phase then carries support to 31 December 2030, after which only customer-specific maintenance remains available. A separate transition milestone of 31 December 2033 — SAP ERP, private edition transition (select RISE) is also tracked, pending confirmation. That leaves a workable but finite window; given that SAP transformations routinely run multi-year, scoping and budgeting should be underway rather than deferred.
The resolution to the deadline is migration to SAP S/4HANA (on-premise, private cloud or public cloud) before mainstream maintenance ends, optionally using extended maintenance to buy limited extra time at additional cost.
This explainer is for executives, programme sponsors and anyone building the business case for an S/4HANA move; it frames the dates that every classic SAP ERP customer is planning around.
