ECC to S/4HANA Readiness Score

Is there an approved business case and budget?

Do you know your custom-code volume and complexity?

What state is your data quality and archiving in?

Do you have internal team capacity for the project?

Have you set a target timeline?

Have you chosen a migration approach?

Your S/4HANA migration readiness

Not started — high risk

Focus areas to raise your score

• Build a business case with cost, risk, and ECC end-of-support drivers
• Run an ATC / Code Inspector inventory to size remediation — the #1 cost driver
• Start data cleansing and archiving to shrink migration scope and downtime
• Secure dedicated capacity or partner support before kickoff
• Set a target go-live working back from the 2027 ECC mainstream-support deadline
• Decide brownfield vs greenfield vs selective transition based on your landscape

Indicative only. A real readiness assessment validates these answers against your actual landscape, custom code, and integrations — and turns the gaps into a costed roadmap.

The 2027 clock and what readiness means

SAP ends mainstream maintenance for ECC in 2027 (extended support to 2030, and a paid option to 2033). Readiness is less about the deadline and more about knowing your custom-code volume, data quality, approach, and team capacity early — the teams that start scoping now avoid the rushed, expensive projects. If staying on ECC longer is part of your plan, see our ECC extended support planning; when you are ready to move, our S/4HANA migration services begin with a full readiness assessment. You can also estimate the cost of the move.
