ECC → S/4HANA

Plan and run your move from SAP ECC to S/4HANA ahead of the December 2027 end-of-mainstream-maintenance deadline — with the conversion approach that actually fits your landscape, and custom code remediated to clean-core standards on the way.

What we do

  • Readiness assessment: simplification items, custom-code impact, data quality and sizing
  • The right conversion path for you — brownfield (system conversion), greenfield (new implementation), or selective data transition
  • Custom-code remediation to S/4HANA and clean-core standards (ABAP Cloud where it fits)
  • Functional adoption of the S/4HANA simplifications that matter to your processes

Why the 2027 deadline matters

Mainstream maintenance for SAP ECC / Business Suite 7 ends December 31, 2027. That is not far away for a programme of this size, and the nearer it gets the scarcer good SAP capacity becomes. Starting now means you choose your path deliberately — and clean up custom code and data while there's time — instead of running a rushed, risk-laden conversion against the clock.

Our approach

Staged, disciplined, low-risk.

No big-bang gambles. Every migration runs in controlled stages with a working fallback at each one.

  1. Assess

    We run the readiness analysis — simplification items, custom code, data, sizing — and recommend brownfield, greenfield or selective with a clear rationale.

  2. Design

    We design the target: processes to adopt, custom code to remediate or retire, and the clean-core boundaries.

  3. Convert

    We execute the conversion in a sandbox-first, iterative cycle, with test cycles and a measured dress rehearsal before go-live.

  4. Stabilize

    We support hypercare, tune performance, and hand over a documented, clean landscape.

What you get

A clean landing, not a lift-and-shift of your technical debt.
