The clock is running on SAP ECC. Mainstream maintenance for SAP ECC ends in 2027, with optional extended maintenance to 2030 at additional cost. For most enterprises that means one thing: the decision — and the planning — needs to happen now, not later.
Why you should not wait
Migrations to SAP S/4HANA Cloud are not a like-for-like technical swap; they are a chance to shed years of accumulated custom code and re-base on standard, AI-ready processes. The closer you get to the deadline, the scarcer skilled resources become and the more rushed the cut-over. Moving early turns a forced upgrade into a planned transformation.
The real shift: from heavy customization to clean core
The biggest mindset change is moving from highly customized ECC to a clean core. Instead of modifying the system itself, you adopt standard processes and extend through SAP BTP, side-by-side. A clean core is what lets you absorb continuous innovation — and SAP Business AI — without painful re-implementation later.
RISE or GROW for the move?
RISE with SAP (Private Cloud) is the classic soft-landing path for complex, heavily customized estates that need more control. GROW with SAP (Public Cloud) suits organizations ready to standardize on best practices for faster value and lower run cost. Many groups combine them in a two-tier model.
How to de-risk the migration
- Assess your code: inventory custom objects and decide what to retire, standardize or rebuild as clean-core extensions.
- Choose the path: greenfield (fresh standard) vs brownfield (convert) vs selective — based on process fit and data quality.
- Plan data migration: cleanse and map early; audit-ready data is half the battle.
- Deliver with experts on the ground: a forward-deployed team that works in your live context, not a slideware plan.
