SAP Migration

When it comes to SAP S/4HANA, there are a lot of options on how to get there. We nailed it down to three so called transition scenarios. Depending on the deployment model (Cloud, HEC or On-premise) and maturity level (S/4HANA Finance or full S/4HANA Enterprise Management), the path to a digital future looks more like a labyrinth than a straight line.

This is the case, you may have a lot of requirements to carry over and don’t want to digest too many changes at a time. However, you also might be trapped with too many corridors that you want to try out before you even realize that it means changes to your custom coding as well as changes in how your system works today.

As with the SAP Business Suite, enterprises can choose from three possible methods for migrating to SAP S/4HANA: green-field, system conversion, or landscape transformation. In assessing which path is the right path, the target architecture alluded to(“SAP S4HANA: CHART THE ROUTE FOR DIGITAL TRANSFORMATION”). Companies that are already running SAP ERP 6.0 (enhancement package 0 and higher) can migrate directly to SAP S/4HANA with a system conversion.

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, mastered and transactional data are migrated from the legacy system. Thus standard data migration tools and content has to be used.

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.

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.
