What is Data Migration?
Data Migration means that (selected) data is being transferred from a source system to a new target system.
There are two different ways of data migration:
- New Implementation (Greenfield)
- Selective Data Transition to SAP S/4HANA
Within a Selective Data Transition to SAP S/4HANA approach, the target system is typically derived from the original source system, in contrast to a New Implementation, where the system can either be built from the original source system or created as a fresh installation of SAP S/4HANA.
From a data perspective, a New Implementation is generally limited to migrating master data, balances, and open items. A Selective Data Transition to SAP S/4HANA also allows the migration of closed and historical data.
With the SAP Business Transformation Center, you can perform a Lean Selective Data Transition to SAP S/4HANA.
You will learn in the following lessons and units how this can be done, and which prerequisites are necessary.
