Migration Strategies

Three paths to S/4HANA.
One right for you.

We assess your landscape, your timeline, and your business goals — then recommend the strategy that makes sense.

Start fresh with best practices
Greenfield
Build a new S/4HANA system from scratch, adopting SAP best practices and clean processes. Ideal for companies that want to rethink their processes — not just migrate them.
✓Clean slate, no legacy baggage
✓Adopt SAP best-practice processes
✓Longer timeline, higher business value
✓Best for major transformation
Convert your existing system
Brownfield
Convert your existing SAP ERP system to S/4HANA while preserving configurations, data, and custom developments. The fastest route to S/4HANA.
✓Shorter timeline
✓Preserve existing data & config
✓Lower disruption to operations
✓Best for stable, well-running systems
The best of both worlds
Selective Data Transition
Migrate selective parts of your system — combine a new S/4HANA shell with migrated data and processes from your ERP. Maximum flexibility.
✓Selective process modernization
✓Mix of new & migrated content
✓Highest flexibility
✓Best for complex landscapes
