SAP has set the end of mainstream maintenance for ECC 6.0 at December 2027. We explore what this means for enterprises still running ECC and the fastest paths to S/4HANA.
What Is the SAP ECC 2027 Deadline?
SAP has confirmed that mainstream maintenance for SAP ERP (ECC 6.0) will end in December 2027. After this date, SAP will no longer provide standard support, security patches, or legal change packages for ECC systems.
For the 30,000+ enterprises globally still running SAP ECC, this is not a distant future event — it is an immediate strategic priority. With typical S/4HANA migrations taking 12–24 months, companies that haven't started planning by mid-2025 are already at risk of missing the window.
What Happens After December 2027?
After mainstream maintenance ends, SAP customers running ECC have two options:
- Extended Maintenance (paid add-on): SAP offers extended maintenance at a premium cost — typically an additional 2–4% of your annual license fee. This buys time but does not solve the underlying problem.
- Migrate to S/4HANA: The only long-term solution. SAP S/4HANA is the next-generation ERP, offering real-time analytics, simplified data model, and built-in AI through Joule.
Staying on ECC beyond 2027 without extended maintenance means no security patches — a critical business and compliance risk.
Why Companies Are Delaying — And Why That's Dangerous
Despite the clear deadline, many enterprises are still on the fence. Common reasons include:
- Perceived high cost and effort of migration
- Fear of business disruption during go-live
- Shortage of internal SAP expertise
- Uncertainty about which migration path to choose
The danger of further delay is real. As 2027 approaches, the market for qualified SAP consultants will tighten dramatically. SAVIC is already observing increased demand for S/4HANA migration resources across India, UAE, and Africa.
Your Three Migration Paths to S/4HANA
1. Greenfield (New Implementation)
Start fresh with a clean S/4HANA implementation. Best for companies wanting to redesign business processes and adopt SAP best practices. Typically 12–18 months.
2. Brownfield (System Conversion)
Convert your existing ECC system to S/4HANA, retaining historical data and custom configurations. Faster than greenfield, typically 6–12 months. Ideal for companies with heavy customizations.
3. Selective Data Transition
Migrate selective data and business processes to a new S/4HANA system. Combines the best of both approaches. Suitable for large enterprises with complex landscapes.
