SAP Commerce EoMM: What It Means and What You Need to Do Now

If you run SAP Commerce on-premises, you have a deadline you cannot ignore: July 2026. That is when SAP ends Mainstream Maintenance for SAP Commerce (formerly Hybris) on-prem. After that date, your platform enters a very different support reality.

This is not a distant problem. It is happening now. And the companies that act early will spend less, disrupt less, and land in a stronger position than those who wait.

What EoMM actually means

End of Mainstream Maintenance (EoMM) does not mean SAP switches off your servers. Your storefront keeps running. But here is what changes:

• No more feature packs. SAP stops delivering new functionality for the on-prem version. Every competitor that upgrades will pull ahead of you.
• Security patches become optional for SAP. Critical vulnerabilities may still get patches, but non-critical ones will not. Your attack surface grows with every passing month.
• Support cases get deprioritised. SAP focuses engineering resources on SAP Commerce Cloud. On-prem tickets go to the back of the queue.
• Custom support is expensive. Extended maintenance (Customer-Specific Maintenance) is available but comes at a premium — typically 2-4% on top of your existing fees — and still does not include new features.

In practice, EoMM means your platform starts falling behind on day one. The gap between where you are and where the market expects you to be widens every quarter.

The three paths forward

Every SAP Commerce on-prem customer faces the same decision tree. There are only three realistic options.

Path 1: Migrate to SAP Commerce Cloud

This is the most common choice — and for good reason. SAP Commerce Cloud is the direct successor. Your existing data models, business logic, and integrations carry over. The platform runs on SAP’s managed infrastructure with automatic updates, built-in CDN, and elastic scaling.

Best for: Companies that have invested heavily in SAP Commerce customisations and want to preserve that investment while gaining cloud benefits.

Timeline: 3-6 months for a typical migration. We completed the Franke migration in 90 days — proof that speed is achievable when the approach is right.

Path 2: Go composable

Some companies use EoMM as the trigger to rethink their entire commerce architecture. A composable approach replaces the monolithic SAP Commerce platform with best-of-breed services: a headless CMS, a separate PIM, an independent order management system, and a modern frontend framework.

Best for: Companies with strong internal development teams, complex multi-brand requirements, or a clear need for frontend flexibility that SAP Commerce Cloud does not provide.

Timeline: 6-12 months depending on scope. Requires more upfront architecture work.

Path 3: Extend support and decide later

SAP offers Customer-Specific Maintenance beyond July 2026. You keep running on-prem, pay more for diminishing support, and push the migration decision into the future.

Best for: Companies that genuinely cannot migrate by July 2026 due to regulatory freezes, M&A activity, or resource constraints.

Risk: This path gets more expensive every year. The talent pool for on-prem SAP Commerce is shrinking. The cost of eventually migrating only goes up.

Why waiting is the riskiest option

We hear this from prospects regularly: “We’ll deal with it after the deadline.” Here is why that logic backfires.

Costs compound. Extended maintenance fees start immediately after EoMM. Meanwhile, your internal teams spend more time patching, monitoring, and working around limitations that a cloud platform handles automatically.

Talent disappears. SAP Commerce on-prem developers are not growing in number. The experienced ones are moving to cloud projects. Finding and retaining on-prem specialists gets harder and more expensive every quarter.

Security exposure grows. Without regular patches, your platform becomes a liability. A single breach costs more than a full migration.

Business agility suffers. Your marketing team wants a new checkout flow. Your product team needs better personalisation. On a frozen platform, every change is a custom development project. On Commerce Cloud, many of these capabilities come out of the box.

The decision framework

Use this simple framework to guide your choice:

1. Audit your customisations. How many are still business-critical? How many are workarounds for limitations that Commerce Cloud has already solved?
2. Assess your integration landscape. What connects to your commerce platform? ERP, PIM, CRM, payment providers, logistics? Map every dependency.
3. Calculate your real TCO. Include not just licence fees but infrastructure costs, internal staffing, opportunity cost of delayed features, and security risk.
4. Set a target date. Work backwards from July 2026. If you need 4 months to migrate, your project kickoff is March 2026 at the latest.
5. Talk to someone who has done it. We migrated Franke from SAP Hybris to Commerce Cloud in 90 days and won an SAP Quality Award for the project. That experience is directly transferable to your situation.

90 days is enough — if you start now

The Franke project proved that a focused, well-planned migration can happen in three months. Not years. Not even six months. Ninety days from kickoff to go-live.

The difference between companies that migrate smoothly and those that scramble? Timing. The ones who start now choose their pace. The ones who wait have the pace chosen for them.
