SAP Migration to S/4HANA Private Cloud

Your Structured Path from Legacy SAP to S/4HANA

With mainstream maintenance for older SAP systems winding down, Keyush guides you through a migration to S/4HANA Private Cloud using the approach that fits your business best.
Organisations still running SAP ECC or earlier releases face a decision — not whether to move to S/4HANA, but how. Keyush helps you choose and execute the right migration path to S/4HANA Cloud, Private Edition, balancing speed, cost, and how much process change your business is ready to absorb.

Choosing the Right Approach

SAP Migration Approaches
Approach What It Means Best For
Greenfield A fresh S/4HANA build on standard, pre-configured processes — no legacy configuration carried forward. Businesses that want to simplify, standardise, or move away from a heavily customised legacy system.
Brownfield A technical conversion of your existing SAP system, carrying forward configuration, custom code, and historical data. Businesses that want a faster, lower-risk path while preserving existing investments.
Bluefield (Selective Data Transition) A hybrid path—selectively migrating chosen processes and data while re-engineering others. Businesses that want to modernise specific areas without a full rebuild.

FAQs

How do we know which migration approach is right for us?
We assess your current customisation levels, data quality, and appetite for process change, then recommend the approach — or a tailored mix — that best balances speed, cost, and risk.
Mainstream maintenance for older SAP ERP releases is being phased out, so organisations still on ECC should be actively planning their migration now to avoid extended-maintenance costs or support gaps.
Brownfield is designed to minimise disruption by preserving existing configuration and custom code — it’s a technical conversion rather than a process redesign, though some adaptation to the new data model is needed.
