SAP ADVISORY · ECC TO S/4HANA
SAP ECC end of life: what CFOs and
CIOs need to know before 2027
Mainstream maintenance for SAP Business Suite 7, including ECC, ends December 2027. Here’s a plain look at the deadline, the RISE with SAP structure, and the commercial details worth independent review before you sign anything.
If you're running SAP ECC, the calendar has already made part of this decision for you. What's left to decide is how you move, on what timeline, and on whose commercial terms. This piece lays out the facts as they stand.
The deadline, plainly stated
SAP has set December 31, 2027 as the end of mainstream maintenance for core Business Suite 7 applications, including ECC. After that date, ECC customers lose standard support — patches, updates, and the usual vendor safety net. An extended maintenance option exists, but it comes at a premium and is designed as a bridge, not a destination.
A full enterprise S/4HANA migration typically takes 18 to 36 months. Organizations that want to be live before the deadline need to be in active assessment now, not next year. Separately, tightening regulatory expectations around financial reporting speed and granularity, along with the retirement of experienced ECC specialists from the workforce, are narrowing the option of indefinite delay.
THE REAL COST OF DELAY
What waiting actually costs
~3x
projected gap between S/4HANA specialist demand and supply by 2027
30–50%
expected rise in consulting day rates through 2026–27
~8%
of completed S/4HANA migrations that finish on the originally planned schedule
The typical migration runs about 30% longer than planned, and budgets are exceeded in more than 60% of cases. The usual causes aren’t exotic technology failures — they’re scope creep, weak data migration planning, and unclear governance. All three are manageable with the right assessment work done up front.
Understanding RISE with SAP
RISE with SAP is SAP’s bundled subscription: software, managed infrastructure, and services combined into a single commercial contract. It is not a hyperscaler product, and it is not itself a migration service. Customers still choose the underlying hyperscaler — AWS, Azure, or Google Cloud — and the technical migration work is carried out on top of the RISE contract by a systems integrator.
What’s included typically covers SAP S/4HANA Cloud Private Edition, SAP Business Technology Platform for integration and analytics, SAP Business Network (including Ariba), and SAP Joule, SAP’s generative AI assistant, at no additional license cost. Partner-delivered migration and implementation services, plus SAP Basis administration, round out the package.
DUE DILIGENCE
Four commercial details worth independent review
The Azure default
In many regions, SAP's commercial structure defaults Business Technology Platform delivery to Azure, even when the customer intends the compute layer to run on AWS. This needs to be caught and corrected before signature, not after.
The managed services markup
SAP's managed infrastructure layer is estimated to mark up true infrastructure cost by 30 to 50 percent compared with open-market rates.
Migration credit scope
Credits bundled into RISE deals typically cover only one initial deployment, billed at SAP's own rates rather than competitive consulting rates.
Existing cloud commitments
Enterprises with existing AWS commit-to-consume agreements can often apply RISE-related spend toward those volume commitments — a lever that is easy to miss without someone specifically looking for it.
Why the hyperscaler choice matters
The AWS-SAP relationship dates back to 2008 — longer than any other major cloud provider has run SAP workloads — spanning joint work on reliability, deployment simplification, and more recently AI co-innovation through Joule and BTP integrations. AWS was the first cloud to offer SAP-certified 32TB HANA instances, and SAP’s own migration of HANA Cloud onto AWS Graviton processors produced a 30 percent performance improvement for analytical workloads.
Independent research from IDC found that organizations running S/4HANA on AWS experienced 58 percent fewer productivity losses from unplanned outages compared with their prior on-premises environments — a data point that belongs in a risk assessment as much as an architecture review.
IDC Research
A practical starting point
None of this requires committing to a multi-year program on day one. A disciplined first phase typically runs two to four weeks and gives both finance and IT leadership a shared, evidence-based business case before any larger commitment is made.
Independent contract review
A close read of the RISE Order Form and contract terms, before anything is signed.
Current-state landscape audit
A clear-eyed look at what's actually running today, and what it will take to move it.
