SAP's announcement of end-of-life for ECC (ERP Central Component) by 2027 — with extended maintenance available until 2030 at additional cost — has sent CIOs scrambling. Some are panicking. Others are pretending it's not happening. Neither response is useful.
I've now been through this process multiple times as an operator, advisor, and fractional CIO. Here is what I know to be true.
What "End of Life" Actually Means
SAP will stop delivering standard patches, legal updates, and new features for ECC after 2027. If you opt into extended maintenance (at a premium price), you get patching support only — not enhancement packs, not new functionality, not regulatory updates beyond what's contracted.
In practical terms: your ECC system will keep running. But it will slowly become a liability. Security vulnerabilities won't be patched. Regulatory changes in payroll, tax, and finance won't be reflected. And every year you wait, the migration pool of consultants shrinks while the complexity of your system grows.
The Three Realistic Options
1. Migrate to S/4HANA
This is SAP's preferred path, and for most organisations with a real long-term SAP strategy, it is the right one. But it is not simple, not cheap, and not fast. A mid-sized company with reasonable ECC complexity should budget 18–36 months and eight figures for a proper migration. Anyone quoting you less deserves a second look.
2. Move to a Different Platform
Oracle, Workday, Microsoft Dynamics, and others have been aggressively targeting the SAP installed base. For some companies — especially those in industries where SAP's strengths (complex manufacturing, multi-entity consolidations, global supply chains) are less relevant — this is worth serious evaluation. Do not let loyalty to a vendor drive a multi-million-dollar decision.
3. Extend and Delay
Some organisations will pay for extended maintenance and buy time. This is not necessarily wrong — if you are mid-way through another transformation, or facing a market disruption, deferring is a legitimate risk decision. But it must be a conscious choice with a defined end point, not a default response to avoiding hard conversations.
What You Should Be Doing Right Now
Regardless of which path you choose, there are things every CIO running ECC should be doing today:
- Clean your data. Your SAP system has years of accumulated junk. Any migration will surface it, and a migration is the worst possible time to deal with data quality for the first time.
- Map your custom code. Most ECC systems have significant customisation. Identify and rationalise it before you start. Custom code is the single largest hidden cost in any S/4 migration.
- Audit your integrations. Every third-party system connected to ECC is a migration dependency. Get visibility now.
- Evaluate your partner landscape. Experienced SAP migration teams are in short supply. The best ones are booking up. Waiting 18 months to start a vendor selection is no longer viable.
- Build the business case. Not for SAP. For your board and CFO. What does it cost to stay? What does it cost to move? What is the risk-adjusted view?
A Word on Timeline Optimism
I have sat in enough project steering committees to know that SAP migrations almost always take longer than planned. Not because of the technology — S/4HANA is a mature platform — but because of the organisational change required. Moving to S/4 is not a technical exercise. It is a business transformation that uses technology as its vehicle.
Plan accordingly. And start sooner than feels comfortable.
The companies that navigate this transition well are the ones that treat it as a business programme, not an IT upgrade. The CIOs that struggle are the ones who hand it to their SAP team and assume the business will follow.
If you're unsure where to start, start with an honest assessment of where your ECC system actually stands — technical debt, data quality, integration inventory, and business appetite for change. Everything else flows from that.
