December 31, 2027 ends mainstream maintenance on ECC. SAP's commercial team is using the deadline as negotiation pressure. Three migration paths, eight clauses to redline, and a deliberate sequence that recovers 25 to 35 percent against the publisher's opening RISE proposal.
The SAP S/4HANA conversion conversation is the largest single commercial event most SAP customers will run between now and 2030. The headline pressure is the December 31, 2027 end of mainstream maintenance on ECC 6.0, which is real but is also negotiation theater.
SAP's commercial team uses the deadline to compress the customer's preparation timeline and to bundle the migration commitment with indirect access exposure, RISE tier deployment, and contractual restructuring into a single conversation.
The buyer side framework treats the conversion as four separate decisions, runs each on its own merits, and recovers 25 to 35 percent against the publisher's opening RISE proposal.
This guide covers the framework.
The 2027 deadline and what it actually means, the three migration paths and the trade offs between them, how migration credits work, the indirect access defense that the German automotive case illustrates, the RISE tier modeling, the negotiation choreography across the eighteen to twenty four month preparation window, the eight clauses worth redlining, and the named pitfalls.
For the worked outcome read the German automotive case study. For the broader SAP context read the SAP services practice. For the operational sizing run the RISE TCO calculator.
SAP announced the end of mainstream maintenance for ECC 6.0 in 2014, originally scheduled for 2025 and subsequently extended to December 31, 2027 in response to customer pushback.
After the mainstream maintenance end date, ECC customers enter extended maintenance which carries a 2 percent premium per year and a defined end date of December 31, 2030. The deadline is real but the consequences are commonly overstated by SAP's account team.
Extended maintenance keeps the system supported and operational. It does not force a migration. The deadline creates time pressure, not technical urgency.
| Date | Event | Customer position |
|---|---|---|
| December 31, 2027 | End of mainstream maintenance for ECC 6.0 | Continue with extended maintenance or migrate to S/4HANA |
| 2028 to 2030 | Extended maintenance period | 2% premium annually. Operational coverage continues. Migration timing is customer's choice. |
| December 31, 2030 | End of extended maintenance | Customers running on third party support continue indefinitely. Customers needing SAP support must have migrated. |
SAP offers three commercial paths from ECC to S/4HANA. Each one has a defined commercial structure, a defined customization tolerance, and a defined operational model. The choice depends on the customer's existing customization scope, the hosting strategy, and the long term commercial preference between subscription and perpetual.
| Path | Commercial structure | Customization tolerance | Best fit |
|---|---|---|---|
| RISE Public Edition | Subscription, fully SAP managed | Low. Standard processes, limited custom code. | Customers ready to consolidate to standard SAP processes, lower TCO priority. |
| RISE Private Cloud | Subscription, hyperscaler hosted, more flexible | Medium to high. Custom code allowed within SAP's framework. | Customers with meaningful customization who want subscription economics. |
| On premise S/4HANA | Perpetual license + 22% annual maintenance | High. Full customer control over customization. | Customers with heavy customization, regulated workloads, or strong data residency requirements. |
SAP's commercial team frames RISE as the default for every ECC customer migrating to S/4HANA.
The buyer side reading is that RISE Public Edition fits about 30 to 40 percent of enterprise customers operationally, RISE Private Cloud fits another 30 percent, and the remaining 30 to 40 percent are better served by on premise S/4HANA with their existing perpetual license model.
The path choice is operational and commercial, not aspirational. Customers who default to RISE because the publisher prefers it lose negotiation leverage and frequently land on a path that does not match their estate.
Migration credits are the contractual mechanism by which SAP applies a portion of the customer's existing ECC investment toward the new S/4HANA license cost.
The credit is calculated as a percentage of the customer's existing perpetual license fees and is applied either as a one time discount against the new contract value or as a multi year offset against subscription fees in a RISE migration.
The standard credit ranges from 30 to 60 percent depending on the migration path, the contracted commitment, and the negotiation. The credit is the largest single commercial lever in the conversion conversation.
| Path | Standard credit | Negotiated credit (well prepared) | Conditions |
|---|---|---|---|
| RISE Public Edition | 40 to 50% | 55 to 65% | Higher credit for committed migration timeline and full ECC retirement |
| RISE Private Cloud | 30 to 45% | 45 to 60% | Higher credit for multi year subscription commitment |
| On premise S/4HANA | 20 to 35% | 35 to 50% | Higher credit when paired with new module purchases |
S/4HANA conversion conversations frequently surface indirect access exposure that the customer was unaware of, because the migration scoping process documents the integration estate. SAP introduced the Digital Access framework in 2018 to license indirect access on a per document basis rather than per user.
The framework defines nine document types (sales orders, invoices, delivery notes, material documents, time sheets, financial postings, manufacturing orders, quality notifications, and service notifications) that count toward licensable consumption when created by a third party system.
The buyer side defense reclassifies the integration estate into three categories. Document creator connections that genuinely require Digital Access licensing. Service consumer connections that read data, execute reports, or call functions without creating documents and do not require Digital Access licensing under SAP's own contractual definitions.
Hybrid connections that require line by line review.
Most enterprise customers find that 30 to 50 percent of the connections SAP scopes as licensable are actually service consumer connections that fall outside the Digital Access framework. The German automotive case study is a worked example of this reclassification, where 4,200 connections reduced to 1,400 licensable connections after reclassification.
RISE is not a single product. It is a tier structure with three primary tiers (Standard, Premium, Premium Plus) plus add ons for specific functional capabilities. SAP's opening proposals frequently default to Premium Plus across the entire estate because Premium Plus produces the highest revenue.
The buyer side framework segments the user population by operational fit and applies different tiers to different populations.
| Tier | Functional scope | Best fit |
|---|---|---|
| Standard | Core S/4HANA functional modules, basic support | Financial accounting, supply chain, HR for most users |
| Premium | Standard plus advanced analytics, embedded process intelligence | Manufacturing, quality, advanced analytics users |
| Premium Plus | Premium plus AI capabilities, premium support tier, full functional scope | Power users in compliance heavy or regulated functions only |
The conversion negotiation runs over eighteen to twenty four months in well prepared engagements. The publisher's account team will encourage compression because the publisher's leverage decays over time. The buyer side framework runs the full timeline because the indirect access analysis and the migration scoping cannot be compressed.
The standard SAP account team line is that the migration credit ratio is fixed policy and not open to negotiation. We disagree. In roughly 6 of 10 conversions we ran, the credit improved materially once the buyer presented a defensible valuation of prior license investment and a credible willingness to delay. The buyer side move is to value your existing entitlements precisely, anchor on a higher conversion ratio, and let the 2027 deadline pressure work on the vendor rather than on your own project timeline.

In an S/4HANA conversion the deadline is shared. The buyer who remembers that negotiates the credit, not just the discount.
December 31, 2027 is the end of mainstream maintenance for SAP Business Suite 7 core applications. After it, customers face extended maintenance fees or must move to S/4HANA, which is why it anchors most conversion negotiations.
New implementation, system conversion, and selective data transition. Each carries different license, data, and project implications, so the path you choose changes the conversion math, not just the timeline.
Migration credits offset the value of your prior SAP licenses against new S/4HANA licenses. The conversion ratio is negotiable, and first offers typically cover 50 to 70 percent of prior value.
Yes. In our engagements the ratio improved once the buyer presented a defensible valuation of existing entitlements and a credible willingness to delay the conversion.
Indirect access is third party or automated use of SAP data. It should be quantified and capped before the conversion is signed, because exposure that surfaces afterward raises the bill with little leverage left.
Only after modeling it against a license plus hyperscaler alternative. RISE bundles infrastructure, licenses, and services, so compare it like for like before committing to the bundle.
Price protection on future uplift, audit scope and notice, renewal caps, and conversion ratio guarantees. These clauses protect the value you negotiated at signing.
Sequence so the 2027 deadline pressure sits with the vendor. Start early, keep your project timeline independent of the commercial talks, and avoid signaling that you must convert by a fixed internal date.
