SAP S/4HANA is a real-time enterprise resource management suite for digital business. It is built on our advanced in-memory platform, SAP HANA, and offers a personalized, consumer-grade user experience with SAP Fiori. Deployable in the cloud or on premise, SAP S/4HANA can drive instant value across all lines of business - no matter your industry or business size.

There are SAP's three transition scenarios for SAP S/4HANA:

• Scenario 1: New Implementation
  This is a new implementation of SAP S/4HANA (green field): customers who are migrating from a non-SAP legacy system or from an SAP ERP system and implementing a fresh system that requires an initial data load. In this scenario, the SAP S/4HANA system is implemented, and master and transactional data are migrated from the legacy system, thus standard data migration tools and content has to be used.
• Scenario 2: System Conversion This is a complete conversion of an existing SAP Business Suite system to SAP S/4HANA (lift & shift): customers who want to change their current SAP ERP system to SAP S/4HANA. This scenario is technically based on Software Update Manager (SUM) with Database Migration Option (DMO) in case the customer is not yet on SAP HANA as the underlying database.
• Scenario 3: Landscape Transformation This is a consolidation of current regional SAP systems into one global SAP S/4HANA system or a split out of different parts of a system: customers who want to consolidate their landscape or carve out selected entities (such as a company code) or processes into a single SAP S/4HANA system.
