Executive White Paper
SAP has drawn a hard line. After December 31, 2027, ECC maintenance ends, no security patches, no legal updates, no support. The organizations that don’t act now will be left behind by competitors already running AI-powered operations on S/4HANA.Â

Inside the Report
Every quarter spent on ECC is not standing still. It's accumulating risk, escalating cost, and widening the competitive gap with organizations that have already migrated.
What December 2027 really means operationally — security, compliance, legal exposure, and why "we'll do it later" is already too late.
Rising technical debt, talent drain, integration failures, and real-world incidents from organizations that ran past end-of-life.
130+ native AI use cases, role generative AI copilots, predictive analytics — and why this capability cannot be retrofitted onto ECC.
How Manufacturing, Retail, Financial Services, and Life Sciences organizations on S/4HANA are outpacing ECC peers — with specific KPIs and case data.
Greenfield vs. Brownfield vs. RISE with SAP — timelines, risk profiles, business case construction, and partner selection criteria.
A complete financial model: direct costs, opportunity costs, competitive gaps, and the point of no return — with your own cost-of-delay calculator framework.
The Numbers Don't Lie

Unique AI use cases in native S/4HANA vs 0 in ECC

Hard stop, even Extended Support ends. There is no post-2030 support available
Organizations that fail to migrate off ECC by 2027 will face rising support costs and increasing competitive disadvantage. The question is not whether to migrate — it is whether to do so on your own terms or under duress.
