SAP mainstream maintenance for ECC ends December 31, 2027. The deadline forces a four way decision. Move to S/4HANA. Pay the extended maintenance premium. Move to third party support. Or run unsupported. The buyer side reference.
SAP mainstream maintenance for the ECC 6.0 product line ends on December 31, 2027. The deadline forces every ECC customer to choose between four paths. Each path has its own price, its own risk, and its own timeline.
SAP extends mainstream maintenance through 2030 for customers that pay a premium. Third party support providers offer support beyond 2030 at a discount to SAP support. S/4HANA migration converts the customer to the new product line.

SAP set the deadline in 2020. The original date was 2025. SAP extended it to 2027 under customer pressure. The 2027 date now stands as the hard cutoff for mainstream maintenance.
Every SAP ECC 6.0 customer. The deadline cuts across industries, geographies, and contract shapes. Customers running ECC on premise, on HANA, or under a private cloud carry the same exposure.
Each path carries its own cost profile, timeline, and risk. The right path depends on the estate size, the transformation appetite, and the regulatory posture.
| Path | Cost vs current | Timeline | Risk profile |
|---|---|---|---|
| S/4HANA brownfield | Plus 30 to 60 percent capex | 18 to 36 months | Project execution risk |
| S/4HANA greenfield | Plus 50 to 100 percent capex | 24 to 48 months | Business transformation risk |
| RISE with SAP | Plus 10 to 30 percent annual opex | 12 to 24 months | Cloud commit lock in |
| Extended maintenance | Plus 2 percent annual fee | Through 2030 | Deferred decision risk |
| Third party support | Minus 40 to 50 percent opex | Indefinite | Exit cost when migrating later |
| Run unsupported | Zero support cost | Indefinite | Security and compliance risk |
SAP offers extended maintenance for ECC through 2030. The premium runs at two percent on top of standard support fees. The math is simple. The trade off is not.
The two percent premium feels small. The strategic cost is not. Every year on extended maintenance is a year of deferred decision. The cliff still arrives in 2030. Customers that defer too long lose the ability to run a structured S/4HANA business case or a clean third party support exit.
Third party support providers offer support for ECC beyond 2027 at a discount to SAP support. The discount runs at fifty to sixty percent on annual fees. The savings compound.
The 2027 deadline is not a technology decision. It is a business model decision. The buyer side discipline is to model all four paths, price them honestly, and pick the path that matches the strategy. The deadline is fixed. The choice is not.
The framework below sets the order of analysis. Run it before any SAP conversation about 2027.
The seven step checklist below is the starting position for any 2027 ECC strategy conversation in the next two quarters.
SAP mainstream maintenance for ECC 6.0 ends on December 31, 2027. SAP stops shipping new legal and tax updates, security patches, and tier one support after that date. Extended maintenance is available through 2030 for customers that pay the premium. The 2027 date is the hard cutoff for mainstream maintenance regardless of customer relationship.
Yes. Two paths exist for staying on ECC past 2027. SAP extended maintenance through 2030 at a two percent premium. Or third party support from providers such as Rimini Street and Spinnaker Support. Both options preserve ECC operations. The choice between them turns on cost, patch scope, and the S/4HANA migration timeline.
A brownfield S/4HANA migration runs eighteen to thirty six months for a typical mid sized estate. Greenfield takes twenty four to forty eight months. RISE migration falls between the two timelines because it bundles the conversion with cloud commitment. The actual timeline depends on custom code volume, integration count, and business change appetite.
No. Third party support providers cover ECC only. S/4HANA falls under SAP support and is not covered by Rimini Street or Spinnaker Support today. Customers that plan an S/4HANA migration within three years should weight that timeline carefully against the third party support savings before signing a multi year support contract with a third party provider.
SAP cannot prevent a customer from moving to third party support, but the customer loses access to SAP patches, SAP support, and direct SAP escalation. Returning to SAP support later carries back support fees and uplift. SAP retains the right to audit indirect access regardless of the support shape, so audit posture remains a separate risk.
