Move to S/4HANA with a plan you trust.
Assessment, migration, testing and support for your move from SAP ECC, delivered with SAP Activate and backed by our partnership with PGC Digital.
The ECC clock is running.
SAP mainstream maintenance for ECC 6.0 ends after 2027, with optional extended maintenance to 2030 at extra cost. The migration path you pick decides how much of that time you spend on rework.
A typical brownfield conversion takes 9 to 18 months including testing. Programmes that start in 2027 leave little room for slippage.
Greenfield
NEW IMPLEMENTATIONStart clean on S/4HANA and redesign processes around standard. Best when the old system carries years of custom code.
Brownfield
SYSTEM CONVERSIONConvert your existing ECC system in place. Keeps history and configuration, and is usually the fastest route.
Bluefield
SELECTIVE DATA TRANSITIONCarry over the data and company codes you choose while redesigning the rest. A balance for complex group structures.
Six phases, each with a clear gate.
We follow SAP Activate, the methodology SAP designed for S/4HANA. Every phase ends with a decision point, so there are no surprises at cutover.

RISE with SAP or on-premise?
Both run the same S/4HANA. The difference is who runs the infrastructure and how you pay. We help you compare them on your numbers.
| RISE with SAPS/4HANA Cloud, private edition | On-premiseor customer-managed cloud | |
|---|---|---|
| Infrastructure | Hyperscaler (AWS, Azure, Google Cloud) managed by SAP | Your data centre or your own cloud account |
| Commercial model | Subscription bundling software, infrastructure and technical operations | Perpetual licence plus maintenance; infrastructure bought separately |
| Technical operations | SAP runs basis, backups, patching and upgrades of the platform | Your team or partner runs everything |
| Extensions | Clean core: standard where possible, extensions on BTP | Full freedom to modify, with higher upgrade effort |
| Cost profile | Predictable operating expense | Capital expense with variable running costs |
| Best for | Teams that want to focus on processes, not infrastructure | Strict data residency or heavy existing infrastructure investment |
Modules we migrate and extend.
Finance usually leads, with logistics, manufacturing and HR following in the same programme or in waves.
S/4HANA questions we hear most.
When does support for SAP ECC end?
SAP mainstream maintenance for ECC 6.0 (enhancement packages 6 to 8) runs until the end of 2027. Optional extended maintenance is available until the end of 2030 at an additional fee.
How long does a migration take?
A brownfield conversion typically takes 9 to 18 months including testing. Greenfield and selective transitions vary more with the amount of process redesign.
Can we keep our historical data?
With a brownfield conversion all history comes across. With greenfield you choose what to load. Selective data transition lets you carry over specific company codes or years.
Do we have to move to RISE with SAP?
No. S/4HANA can run on-premise or in your own cloud. RISE bundles software, infrastructure and technical operations into one subscription, which suits many but not all organisations.
What happens to our custom code?
We scan it, remove what is no longer used, adapt what must stay and move suitable extensions to SAP BTP so future upgrades are easier.
Start with a 4–6 week readiness assessment.
You get the custom code picture, the recommended path, a timeline and a costed business case.
