About SAP S/4HANA migration services
SAP S/4HANA migration partners help enterprises move off ECC before maintenance ends, choosing between greenfield rebuilds, brownfield in-place conversions and selective data transitions. Engagements cover business-case and approach selection, data-readiness and custom-code assessment, the conversion or rebuild itself, and post-go-live managed services, frequently delivered into RISE with SAP. The 2027 deadline makes sequencing and partner capacity a primary planning constraint.
How to choose an SAP S/4HANA migration partner
The migration clock is the defining fact of this market. SAP has confirmed that mainstream maintenance for SAP ECC and Business Suite 7 ends on 31 December 2027, with optional extended maintenance through 2030 at roughly a two-percentage-point uplift on maintenance fees. A further RISE with SAP transition option exists beyond 2030 for a limited set of large, complex customers under contract. Running unsupported ECC past these dates means no security patches or compliance updates, so the practical question for most enterprises is not whether to move but which path and partner.
There are three migration approaches. Greenfield rebuilds the system on clean S/4HANA, maximising process redesign but carrying the highest change effort. Brownfield converts the existing system in place, preserving history and customisation at the cost of carrying forward technical debt. A selective or bluefield transition, often delivered with tools such as SNP, moves chosen data and processes selectively. Partner selection should follow the chosen path: finance-led transformations favour Deloitte and the Big Four, while large template-and-factory rollouts favour the global integrators with industrialised migration capacity.
A blunt limitation: S/4HANA programmes routinely overrun on timeline and budget when data quality and custom-code remediation are underestimated, and a brownfield conversion that simply rehosts technical debt can deliver little business value. Insist on a data-readiness and custom-code assessment before fixing scope. For ERP context see the ERP systems category, compare adjacent advisory in ERP advisory and optimisation, review broader SAP implementation services, and use independent comparisons when benchmarking partners.

Frequently Asked Questions
When does SAP ECC support end?
SAP mainstream maintenance for ECC and Business Suite 7 ends on 31 December 2027. Optional extended maintenance runs to the end of 2030 at an additional cost of roughly two percentage points on maintenance fees, and a RISE with SAP transition option exists beyond 2030 for select large customers. Verified June 2026.
What does an S/4HANA migration cost?
Costs vary widely with size and approach. Mid-market brownfield conversions commonly run USD 3M to USD 10M, while large multi-country greenfield programmes reach tens of millions over multiple years. Data remediation, custom-code rework and testing are the largest variable cost drivers. Enterprise pricing requires a quote.
Greenfield, brownfield or selective transition — which is right?
Greenfield suits organisations wanting process redesign and willing to absorb high change effort. Brownfield suits those needing to preserve history and customisation quickly. Selective or bluefield transitions move chosen data and processes and can balance the two. The decision should follow a data and custom-code assessment, not a default preference.
What is RISE with SAP?
RISE with SAP is SAP's bundled offering of S/4HANA Cloud private edition with infrastructure, managed services and tools under one contract. Many partners deliver migrations into RISE, and a RISE transition option now provides a support path for select customers beyond the 2030 extended-maintenance deadline.
Why do S/4HANA programmes overrun?
The most common causes are underestimated data quality issues, the volume of custom code requiring remediation, and insufficient testing. A brownfield conversion that rehosts technical debt without addressing these can finish on a supported platform while delivering little new business value.
