    The December 2027 deadline

    SAP ends mainstream maintenance for SAP ECC in December 2027. That date is the single biggest driver of SAP work right now, and it creates a scheduling problem rather than just a technical one: every ECC customer is working to the same deadline, competing for the same implementation capacity.

    The practical consequence is that timing is part of the decision. Organisations that start planning early get to choose their migration approach on merit and negotiate from a position of choice. Organisations that begin close to the deadline get a compressed timeline, less room for a phased approach, and a scarcer, more expensive supplier market.

    Choosing a migration path

    There are three routes to S/4HANA, and the choice has more to do with the state of your existing system than with technology preference.

    Brownfield — system conversion

    Converts your existing SAP system in place, preserving configuration, historical data and custom development. Lowest business disruption and usually the fastest route. The catch is that it carries your existing technical debt forward, including customisations that may no longer earn their keep.

    Greenfield — new implementation

    A fresh S/4HANA build. This is the right call when your existing configuration has accumulated years of workarounds, or when the business has changed enough that the current setup no longer reflects how it operates. Higher effort, and it is effectively a re-implementation project with change management to match.

    Selective data transition

    A hybrid: a clean core with selected configuration and data brought across. It offers the most control and is correspondingly the most complex to plan. It tends to suit organisations that want a fresh start but cannot abandon specific historical data or well-functioning process areas.

    We assess your current landscape — custom code inventory, data quality, integration surface, and how far your configuration has drifted from standard — and recommend a route based on that evidence rather than a default preference.

    Custom code is usually the deciding factor

    The variable that most often determines effort is the volume and quality of custom ABAP. A custom code assessment early tells you what must be remediated for S/4HANA compatibility, what can be retired because standard functionality now covers it, and what genuinely needs rewriting. This analysis frequently changes which migration path makes sense, which is why it belongs at the start rather than during execution.

    After go-live

    Support and optimisation is a core service line for us, not an afterthought to implementation. That covers performance tuning, Fiori adoption, process optimisation as teams settle into the new system, and ongoing custom development where standard modules need extending.

    Frequently Asked Questions

    Why does the SAP ECC end-of-support deadline matter?

    SAP ends mainstream maintenance for SAP ECC in December 2027. Businesses that wait until close to the deadline face a compressed timeline, higher costs, and reduced vendor support during migration.

    What's the difference between greenfield, brownfield, and selective data transition?

    Greenfield is a fresh S/4HANA implementation from scratch; brownfield converts your existing SAP system in place, preserving configuration; selective data transition is a hybrid of the two.

    Do you support SAP systems after go-live?

    Yes — ongoing SAP support and optimization is one of our core service lines, not just implementation.

    How do we decide between brownfield and greenfield?

    It usually comes down to how much your current configuration still reflects how the business operates. If it does, and your custom code is manageable, brownfield is faster and less disruptive. If your system has accumulated years of workarounds, or the business has materially changed, greenfield avoids carrying that forward. A custom code and configuration assessment gives you the evidence to decide rather than guessing.

    What happens to our custom ABAP code?

    It gets inventoried and classified: compatible as-is, needs remediation for S/4HANA, superseded by standard functionality and therefore retirable, or requires a rewrite. In most estates a meaningful proportion turns out to be retirable, because standard S/4HANA covers what the customisation was originally written for. Doing this analysis early frequently changes the effort estimate for the whole project.

    Is S/4HANA worth it if we are happy with ECC?

    Being happy with ECC is a reasonable position, but it stops being a strategy in December 2027 when mainstream maintenance ends. Running unsupported ERP creates security, compliance and audit exposure. The realistic choice is not whether to move but when — and moving on your own timeline is materially cheaper than moving on a deadline.

    Can we migrate in phases rather than all at once?

    Partly. The technical move to S/4HANA has a definite cutover, but the surrounding programme can absolutely be phased — pilot entities or geographies first, Fiori adoption and process optimisation staged afterwards, and integrations migrated on their own schedule. We plan the sequence around your risk tolerance rather than treating it as one indivisible event.

    What is the most commonly underestimated part of an SAP migration?

    Interfaces. Attention usually concentrates on the core system, while the connections to warehouse, banking, e-commerce, tax and reporting systems get treated as a detail. In practice they carry substantial embedded business logic, they are often poorly documented, and rebuilding them takes longer than expected. We inventory the integration surface during assessment for exactly this reason.

    Do you work alongside our existing SAP team or partner?

    Yes. Many organisations have internal SAP capability or an incumbent partner and need specific help — a readiness assessment, custom code remediation, integration work, or extra capacity for a defined workstream. We are comfortable scoping to a clear boundary rather than requiring ownership of the whole programme.
