SAP S/4HANA Migration

A planned path from SAP ECC to S/4HANA

We assess your current landscape, help you choose the right route and handle data, custom code and cutover step by step.

Overview

Move to S/4HANA without losing what already works

Migrating is not only a technical upgrade. It is a chance to clean up data, retire unused customisations and simplify processes. The risk lies in surprises, so we start with an assessment that shows what the move will involve before any commitment is made.

Migration paths

Three ways to get to S/4HANA

There is no single right answer. The assessment helps you choose.

System conversion

Move your existing SAP system to S/4HANA in place, keeping your processes and history. Suits landscapes that are in good shape and heavily used.

New implementation

Build a fresh S/4HANA system and bring over only the data you need. Suits organisations that want to redesign processes and drop old customisations.

Selective data transition

Move chosen companies, business units or data sets to S/4HANA while leaving others behind. Suits mergers, carve-outs and phased programs.

What we handle

The parts of a migration that need care

Readiness assessment

A review of your current system, add-ons, customisations and data to show what the move involves.

Data migration

Cleansing, mapping, loading and reconciling data so the new system starts with trusted numbers.

Custom code adaptation

Finding and adjusting custom programs so they work on S/4HANA, and retiring the ones you no longer need.

Interfaces and integrations

Checking and reconnecting the systems that exchange data with SAP.

Testing

Regression and business-scenario testing to confirm nothing important breaks.

Cutover planning

A rehearsed cutover plan that keeps downtime as short as practical.
