Move to S/4HANA without the cliff edge.
Brownfield, greenfield or selective data transition. We choose the route from your data, your deadlines and your appetite for change, then rehearse cutover until go-live feels routine.
What gets in the way.
ECC support is ending, custom code has grown for years, and every partner has a different opinion. Most organisations don’t lack options. They lack a clear, trusted view of which route fits them.
The work, end to end.
- S/4HANA readiness assessment: custom code, simplification items, data quality and integrations
- Migration strategy and business case: brownfield, greenfield, selective data transition or RISE with SAP
- Custom code remediation and clean core clean-up
- Data migration: cleansing, mapping, loads and reconciliation
- Testing strategy and execution, including regression and performance
- Cutover planning and rehearsals
- Go-live and hypercare
AI-assisted code analysis sorts custom objects into keep, rework or retire. Test scripts are generated and checked faster, and Joule use cases are planned into the target design from the start.
Every AI output is reviewed by a senior SAP consultant.
A clear route and budget in weeks, a lower-risk cutover, and a cleaner system after go-live than you had before it.
Good questions.
How long does a migration take?
It depends on the size of your system and the route. A mid-sized brownfield conversion typically runs [X to Y] months. Our readiness assessment gives you a realistic timeline for your own landscape.
Should we go with RISE with SAP?
Sometimes. We explain what RISE with SAP includes, what it leaves to you, and how it compares with the other options, without selling you a licence.
Can you work alongside our existing SAP partner?
Yes. We often act as an independent adviser or as a specialist delivery team next to an existing partner.
When does ECC support end?
Mainstream maintenance for SAP ECC 6.0 ends at the end of 2027. Optional extended maintenance runs to the end of 2030 at additional cost.
