The 2027 deadline

The SAP ECC end-of-life deadline

SAP has confirmed that mainstream maintenance for SAP ECC (Business Suite 7) ends in 2027, with optional extended maintenance available until the end of 2030. Every SAP customer now faces the same decision: how, and when, to move to SAP S/4HANA. Whichever route you choose, one question follows you through the whole programme – what happens to the decades of historical data sitting in your old ECC system? You rarely need it running day to day, but you cannot simply delete it. Cella is the answer to that question.

How Cella fits

Decommission SAP ECC as you migrate to S/4HANA

  • Migrate less. Move only current, in-scope data into S/4HANA and leave the historical burden behind.
  • Cut your HANA and RISE footprint. Keep years of legacy data out of your most expensive platform.
  • Keep every record. Historical data stays accessible for statutory retention, audit and reporting.
  • Reduce risk and cost. A smaller, cleaner migration is faster to deliver and lower risk.
  • AI-ready history. Freed from the legacy system, your historical data is clean and governed – ready for AI and analytics when you are.
Every route to S/4HANA

Greenfield, brownfield or bluefield

There is no single way to reach S/4HANA, and Cella complements all of them.

Greenfield

A fresh start

A new S/4HANA implementation built from scratch. Cella decommissions the ECC system you are leaving behind, retaining its full history without carrying it into the new build.

Brownfield

In-place conversion

A system conversion of your existing ECC to S/4HANA. Use Cella first to archive and remove data you do not need to convert, so the brownfield migration is lighter and lower-risk.

Bluefield / selective

The hybrid route

A selective transition that moves only chosen data. Cella holds everything you choose to leave behind, so “selective” never means “lost”.

SAP mainstream maintenance for SAP ECC (Business Suite 7) ends in 2027, with optional extended maintenance typically the end of 2030 for customers who have not contracted to RISE. After that, customers must move to SAP S/4HANA or a third-party support arrangement. The deadline is the main reason organisations are planning their S/4HANA migration now.

A greenfield migration is a fresh S/4HANA implementation built from scratch, leaving the old ECC system behind. A brownfield migration is an in-place conversion of your existing ECC system to S/4HANA, carrying its configuration and data across. A bluefield or selective approach sits between the two, moving only chosen data. Cella supports all three by decommissioning the legacy data you do not migrate.

No. Most organisations only need current, in-scope data in S/4HANA. Historical data kept for reporting, audit or compliance can be decommissioned into Cella, keeping it fully accessible while your new system stays lean and lower-cost.

RISE with SAP is SAP’s bundled offering that brings S/4HANA Cloud, infrastructure and managed services together in one subscription. Because pricing reflects the size of your system, decommissioning legacy data with Cella before you move helps keep the ongoing RISE cost down.

Cella extracts historical data from your legacy SAP system into one secure, reportable store, so your migration to S/4HANA carries only the data you need. The old system is switched off, and its data stays accessible for reporting, audit and compliance.
