The greenfield-versus-brownfield question has no universal answer. A clean reimplementation buys you simplicity at the price of disruption; a system conversion preserves your history at the price of carrying old decisions forward. We help you choose on evidence, then deliver either path.
For S/4HANA journeys specifically, we assess your custom code, data volumes, process debt and business appetite before recommending a route — and we will tell you if the honest answer is a hybrid, selective approach.
Our approach
- Assessment decides the route. Custom-code analysis, data profiling and process-debt review pick the path on evidence.
- Greenfield: design freedom used deliberately. Standard-first design, clean master data, only justified customisation.
- Brownfield: conversion without carry-over. We use the conversion to retire dead code and clean data along the way.
- Business continuity throughout. Month-end still closes, orders still ship, payroll still runs — through every phase.
Typical engagements
- Greenfield S/4HANA implementations for growing enterprises
- Brownfield ECC-to-S/4HANA system conversions
- Selective data transition projects combining both approaches
- New-entity builds inside an existing corporate template
What you can expect
- A defensible route decision with the trade-offs documented
- A landscape ready for the 2030 ECC maintenance horizon
- Less custom code and cleaner data than you started with
