Data migration often starts as a technical workstream. Tight timelines, shared ownership, poor data quality and siloed knowledge can quickly turn it into a risk for the entire ERP transformation.
Migration tests rarely run without errors on the first attempt. But when the defect backlog grows with every test cycle and no pattern emerges, the migration lacks a structured approach.
Historical source data causes delays long before the first load cycle is complete. Without early structure, data issues surface too late and take far more effort to resolve.
When validation starts too late in the migration process, test cycles lose much of their value. In the worst case, defects only become visible during the final cutover migration.
When a migration grows out of isolated decisions, fixes and workarounds, the result is impossible to trace. That prevents the team from learning systematically between cycles.
The client did not need another Excel process for its new S/4HANA landscape. It needed a migration environment that made mock runs, loads and validation repeatable. We consolidated data from around 200 source tables and built the transformation logic across several business functions.
Outcome: less manual rework, clearer defect analysis and reliable cycles through cutover.
Have your migration planned, delivered and validated as one coherent project, with clear ownership throughout.

We turn incomplete, legacy or inconsistently structured source data into clean target data for your new ERP, regardless of the source and target systems involved.
Data, mappings, validation and exports stay in one shared environment instead of disappearing between Excel files, emails and tool interfaces. Every migration cycle remains traceable.
Our migration process connects business decisions, technical transformation logic and validation feedback, so every cycle improves the next.
We analyse the migration scope, relevant data objects, source systems and target structures. This becomes the plan for which data must move under which rules.
We translate your teams’ business requirements into technical selection criteria, transformation rules and value mappings that control the migration logic.
Selection criteria, transformation rules, value mappings and business requirements become repeatable migration logic, including pre-load validation and plausibility checks.
Each migration cycle produces findings from validation, load errors and business feedback. We use them to improve the migration logic for the next cycle.
In-house teams and consultants value us as an external project partner for complex ERP migrations.
Mathieu helped our European ERP programme turn different Navision standards into a consistent data foundation for SAP S/4HANA RISE. His ability to translate business requirements into scalable migration logic, validation and governance was particularly valuable.
John M.CIO @ OSI Group
Mathieu made a clear difference to our S/4HANA implementation, both technically and operationally. He captured complex requirements independently, developed the solution and delivered it without defects. As Data Migration Lead, he found practical answers to day-to-day project challenges quickly.
Benjamin B.Project Management @ thyssenkrupp
Across several S/4HANA transformation projects, Mathieu proved himself as a highly capable data migration specialist. His knowledge of SQL, SAP migration tools, ETL processes and data validation made him a strong lead for planning and delivering complex migrations.
Marco S.Senior Manager @ IBM Consulting
Mathieu supported a strategically important SAP implementation with a high degree of independence and a clear view of the wider team. He introduced new ways of working and made a noticeable contribution to moving the project forward faster.
Christian H.Group Information Officer (EVP) @ Heraeus
We support enterprise clients and other project partners in the delivery of complex ERP migration programmes.
You speak directly with Mathieu Franke about the scope and setup of your project, clarify open questions and review the available options.
Where useful, we test alternative approaches before kick-off with prototypes based on the structure of your production data, without locking you in.
You receive a non-binding proposal tailored to your requirements, with responsibilities set out clearly.
Once commissioned, we plan and deliver the agreed work together with your project leads.
