Brownfield, greenfield, or selective transition? A free, no-signup quiz — answer six questions about your processes, custom code, and landscape to see which S/4HANA migration approach fits, with a ranked score for all three.
Best-fit migration approach
Brownfield (system conversion)
Convert your existing ECC system in place. Fastest and cheapest path; keeps processes, custom code, and history — including the parts you might not want.
Directional only. The real decision also weighs your custom-code inventory, data volumes, integration landscape, and licensing position — an assessment turns this leaning into a costed recommendation.
The approach question is the first fork in every S/4HANA program, and it drives cost, timeline, and risk more than any other early decision. Brownfield is faster and cheaper but carries your legacy forward; greenfield buys transformation at a premium; selective transition splits the difference with more moving parts. For the full trade-off analysis, read our brownfield vs greenfield guide, then sanity-check the money side with the cost estimator and your preparedness with the readiness score. When you want the leaning validated against your actual landscape, our S/4HANA migration services start with exactly that assessment.
