Brownfield (Migration from SAP ECC), Technically the migration to SAP S/4HANA, cloud edition is based on SAP Landscape Transformation (SLT) and Data Migration Server (DMIS) as data migration tools. Data is migrated from a customer’s source (SAP Business Suite System or any legacy system) to a new SAP S/4 HANA cloud target system. From an implementation point of view, the data migration is integrated into the SAP S/4HANA Implementation Cockpit (End to End Implementation Experience).
