SAP ECC End of Maintenance 2027: Migration Options, Licensing Risks & What to Negotiate

What Exactly Ends in 2027 — and What Does Not

SAP ECC 6.0 mainstream maintenance officially ends on 31 December 2027. For enterprises still running ECC, this means SAP will stop delivering standard corrections, legal and regulatory updates, and security patches under the standard 22% maintenance contract. What gets cut: new software corrections, legal change updates for your jurisdiction, and standard SAP support response SLAs as you know them today.

What does not necessarily end: your ability to run the software. SAP cannot remotely disable ECC. Your licences remain valid. Your system continues to function. The risk is operational — no more security patches, no regulatory compliance updates, no SAP priority support. For regulated industries (financial services, healthcare, energy), that operational risk is real and must be planned for. For others, the urgency is less acute than SAP's commercial team wants you to believe.

SAP has already extended ECC maintenance multiple times — from 2020, to 2025, to 2027. They may extend again, particularly if adoption of S/4HANA falls short of targets. Do not make a multi-million-pound decision based on a deadline SAP has already moved twice. Watch the market, not SAP's renewal pressure.

SAP's Extended Maintenance Trap: The Price of Doing Nothing

SAP's first commercial play for ECC customers is Extended Maintenance (also called Customer-Specific Maintenance). This gives you access to SAP support beyond 2027, but at a significantly higher cost. Historically SAP has priced Extended Maintenance at a 4% annual premium on top of your existing maintenance fees — meaning your annual bill rises from 22% to 26% of your licence value, or higher depending on the negotiation.

Extended Maintenance is not a long-term solution. It typically runs for two to three years, is non-renewable indefinitely, and comes with restrictions: SAP deprioritises support tickets, may not deliver all regulatory updates, and uses the contract as additional leverage to push migration. The Extended Maintenance conversation is frequently positioned by SAP's account teams as a "bridge" — but it is actually a revenue-maximisation tool dressed up as customer service.

Third-party maintenance providers such as Rimini Street and Spinnaker Support offer what amounts to Extended Maintenance for ECC at 50% or less of SAP's current maintenance fees — with arguably comparable support for stable ECC landscapes. That pricing reality is the single most powerful commercial lever you have when negotiating with SAP over an Extended Maintenance contract.

The Hidden Cost in Extended Maintenance Agreements

Read Extended Maintenance Order Forms carefully. SAP sometimes includes clauses that require conversion to S/4HANA or RISE within the extended period, or that exclude specific regulatory updates for your country unless you also purchase additional localisation packages. Extended Maintenance is never simply "more of what you have now" — it is a constrained, time-limited bridge that SAP monetises at premium rates.

Your Four Migration Options — Compared Honestly

Every SAP ECC customer has four substantive paths forward. SAP's commercial team will present two of them — RISE with SAP and S/4HANA on-premise — and will deliberately understate the viability of the other two. Here is an honest comparison.

SAP's commercial interest aligns with RISE with SAP. Every other option reduces SAP's revenue per customer, which is why SAP account teams are incentivised to steer you there. Our RISE with SAP guide provides a full independent analysis of what the contract actually delivers versus what it costs.

Hidden Licensing Risks in Every Migration Path

Regardless of which path you choose, the migration from ECC to any future-state architecture carries significant licensing risk that SAP rarely surfaces proactively. These are the exposures we see most frequently in ECC migration engagements.

1. Named User Type Reclassification in S/4HANA

S/4HANA uses a different user licence model than ECC. In ECC, your Named User types include Professional, Limited Professional, Employee, and Functional users at various price points. In S/4HANA, SAP has restructured these into fewer, higher-cost categories. The migration process — particularly through the SUM (Software Update Manager) or when loading data into a new system — often triggers a reclassification where users who were formerly Limited Professional in ECC become Professional in S/4HANA. SAP's tools will generate an ELP (Effective License Position) that recommends you buy more. Those recommendations are challengeable.

2. SAP BTP Entitlements You Won't Use

RISE with SAP bundles SAP BTP (Business Technology Platform) credits. On paper this looks like added value. In practice, 70% of RISE customers never fully consume their BTP entitlements in the first two years — yet those credits are factored into the total contract cost. If your organisation does not have a clear BTP consumption roadmap at signing, you are paying for credits you won't use. This is one of the most common overpay scenarios we see in RISE deals.

3. Digital Access Exposure During Migration

If your selective modernisation path involves connecting a new SaaS system (Salesforce, ServiceNow, Workday, or similar) to your existing ECC landscape, you must understand SAP's Digital Access licensing model. Any system that generates SAP document types — sales orders, purchase orders, deliveries, invoices, materials — through an interface may trigger Digital Access charges. An ECC-to-cloud migration that introduces new integration points without a Digital Access assessment can create audit exposure even before you have completed the migration. Read more in our SAP Digital Access licensing guide.

4. The Conversion Licence Trap

SAP offers conversion paths from existing ECC licences to S/4HANA licences, often described as "licence exchange" or "conversion credits." The commercial reality is that SAP's conversion pricing typically favours SAP. You will be converting ECC licences — which you own perpetually — into cloud subscription licences you pay for annually in perpetuity. The net present value calculation usually favours the buyer maintaining perpetual licences for longer and delaying migration, which is precisely why SAP discourages this analysis.

Negotiation Strategy Before You Decide Anything

The biggest mistake enterprises make when facing the 2027 deadline is engaging SAP's commercial team before establishing their own independent commercial position. SAP's account teams are experienced negotiators with detailed knowledge of your system landscape, your renewal dates, and your internal politics. Without independent preparation, you are at a structural disadvantage from the first conversation.

Build Your BATNA Before SAP Calls

BATNA — Best Alternative to a Negotiated Agreement — is the foundation of any commercial negotiation. For ECC customers, your BATNA is a credible, documented alternative to whatever SAP is proposing. This means having a real third-party maintenance quote from Rimini Street or Spinnaker. It means having a competitive S/4HANA implementation proposal from a non-SAP channel partner. It means having board-approved optionality to defer. When SAP knows you have alternatives, the commercial conversation changes entirely.

Benchmark SAP's Proposals Against the Market

SAP ECC migration and RISE contracts are not standardised. Two companies of similar size in the same industry can receive proposals that differ by 30-40% in total cost. SAP prices based on what it believes the customer will pay, informed by account team intelligence on budget, timeline pressure, and internal urgency. Independent benchmarking — comparing your proposal against what comparable enterprises have negotiated — is one of the most effective negotiating tools available. Our SAP contract negotiation service provides exactly this benchmarking.

Never Let SAP Control the Timeline

SAP's commercial team will create urgency around the 2027 deadline — suggesting that certain migration incentives, conversion credits, or favourable pricing are only available for a limited window. Some of these incentives are real. Most are negotiating tactics designed to compress your decision timeline before you have completed proper due diligence. SAP has consistently extended incentive programmes and maintenance deadlines. Time pressure that originates from SAP's commercial team is almost always artificially inflated.

Third-Party Maintenance: The Lever SAP Fears

Third-party maintenance (TPM) for SAP ECC is the option SAP least wants you to exercise and most wants you to fear. The two major providers — Rimini Street and Spinnaker Support — offer support for SAP ECC at 50% or less of SAP's current maintenance fees, typically with comparable or better SLA response times and without the pressure to migrate.

SAP will tell you that TPM comes with legal and operational risk. The legal risk largely relates to intellectual property — specifically whether TPM providers are creating custom fixes that incorporate SAP IP without authorisation. SAP has litigated this aggressively, with mixed results. Rimini Street and Spinnaker have both survived major SAP legal challenges and operate with refined engagement models that manage IP risk. The operational risk is real in one respect: you will not receive SAP's software corrections or legal/regulatory updates. For stable, mature ECC landscapes that are not rapidly changing, this risk is often manageable — particularly in the short to medium term.

The commercial power of TPM in negotiation is enormous even if you never switch. A credible, documented TPM quote changes every conversation with SAP. It demonstrates that your organisation has genuine alternatives, that you understand the market, and that you are not going to accept whatever renewal price SAP proposes. In our experience, presenting a TPM option alongside an Extended Maintenance negotiation can reduce SAP's proposed maintenance premium by 40-60%.

Recommended Timeline for Enterprise Buyers

If you are on SAP ECC today, here is how we recommend structuring your planning horizon — independent of SAP's commercial pressure:

Now through H1 2026: Establish your independent commercial position. Commission a third-party maintenance assessment, benchmark your current SAP spend against peers, and conduct an internal assessment of your ECC landscape's technical debt and regulatory exposure. Do this before engaging SAP's account team on any migration conversation. Our SAP licence optimisation service typically begins with this landscape assessment.

H2 2026: Run a formal RFP or options evaluation across all four paths — RISE, S/4HANA on-premise, third-party maintenance + defer, and selective modernisation. Get real commercial proposals. Benchmark all of them. Build a total cost of ownership model that covers a 5-year and 10-year horizon, not just the initial commitment period.

2027: Make your decision from a position of complete commercial awareness, with documented alternatives and a negotiated deal. Do not sign anything in 2025 or early 2026 unless the commercial terms are genuinely exceptional and fully reviewed by independent advisors.

The enterprises that will overpay most significantly on the ECC transition are those that let SAP control the narrative, the timeline, and the options. Independent preparation — starting now — is the most valuable investment you can make before this deadline arrives.
