Can We

Shift S/4
With You?



The OTT SHIFT S/4 methodology allows customers to choose (with our expert guidance) between Greenfield, Brownfield and our SHIFT S/4 Hybrid approach to S/4 HANA Conversions.

  • A new implementation of SAP S/4HANA, also known as a ‘Greenfield’ migration, enables complete re-engineering and process simplification.
  • The Greenfield approach lets organizations predefine migration objects and best practices. It lowers Time-to-Value and TCO and facilitates faster adoption of innovation.
  • System conversion, also known as the ‘Brownfield’ approach, enables migration to SAP S/4HANA without re-implementation and without disruption to existing business processes.

  • At the same time, it enables re-evaluation of customization and existing process flows
  • An accelerated offering combining the best elements of green and brown ­– offering the best time to value as several transformation elements are combined in a single-step approach including proprietary data accelerators and templates.

  • Best for large multi-SAP or non-SAP landscapes needing consolidation into a single SAP S/4 HANA system.

  • Complex data scenarios can be assessed, cleansed and archived using the Hybrid Approach.
