SAP ConsultingIf your company runs SAP ECC, 2027 should already be in the plan. Here we summarize what SAP has announced and how to turn it into concrete decisions.
The key dates
| Date | What happens |
|---|---|
| End of 2027 | Mainstream maintenance ends for SAP ERP 6.0 in its latest enhancement packages (EHP 6 to 8). |
| 2028 to 2030 | Extended maintenance available at an additional cost on the maintenance base. |
| 2031 to 2033 | SAP ERP private edition transition option, with conditions: move to the private edition on SAP HANA before the end of 2030 and purchase additional services. |
Enhancement packages older than EHP 6 have different rules, so confirm the exact version of your system.
What changes if I don't migrate in time?
The system doesn't shut down. What changes is support: without maintenance you stop receiving fixes and legal updates from SAP, and in Mexico that includes tax localization changes. With extended maintenance you stay covered, but you pay more for a system that no longer evolves.
The three paths
- Conversion (brownfield): you keep your configuration and history and move to S/4HANA. It's usually the fastest path.
- New implementation (greenfield): you redesign processes from scratch on S/4HANA best practices.
- Selective approach: you migrate only some company codes, processes or years of history.
What to do in the next 90 days
- Technical inventory: ECC version, database, custom developments and interfaces.
- Data cleanup: duplicate or obsolete customers, suppliers and materials; old open items.
- Review of at-risk modules: for example SAP WM, which in S/4HANA is replaced by EWM or Stock Room Management, and the new fixed asset model.
- Path and budget decision with a phased plan.
