The transition scenario that fits a customer who is interested in moving to SAP S/4HANA Cloud, but is not ready for full process redesign, is selective data transition. Selective data transition is a scenario that allows you to migrate to SAP S/4HANA Cloud from an existing SAP or non-SAP system with minimal disruption and maximum flexibility. You can use selective data transition to select which data, processes, or customizations you want to migrate to SAP S/4HANA Cloud and which ones you want to leave behind or change. You can also use selective data transition to consolidate multiple systems into one SAP S/4HANA Cloud system or split one system into multiple SAP S/4HANA Cloud systems.
