SAP Bluefield migration scenario
The best of both worlds.
Migration to SAP S/4HANA in the SAP Bluefield migration scenario is also known as selective data transfer. This type of migration is a middle ground between new implementation and system conversion. This scenario enables a partial move to SAP S/4HANA or even the consolidation of several SAP systems.

SAP operating models
In principle, all SAP operating models are possible in the SAP Bluefield migration scenario. However, an initial choice must be made between a new implementation and a system conversion. Depending on the choice, a complete cloud solution cannot be implemented initially.
Advantages and disadvantages of the SAP Bluefield migration scenario
Pros
The following advantages speak in favour of the SAP Bluefield migration scenario:
- Migration scope can be specifically defined
- Several SAP systems can be consolidated
- Combination of the advantages of SAP Greenfield-Migration and SAP Brownfield-Migration
Cons
These disadvantages speak against the SAP Bluefield migration scenario:
- Very complex
- SAP or SAP partners and tools that are not freely accessible are required.
- The disadvantages of SAP Greenfield and SAP Brownfield add up
Time for data cleansing
The processes are transferred to the new SAP S/4HANA system, depending on whether the new implementation or the system conversion was initially selected. The inventory data is extracted from the legacy system, filtered and migrated to SAP S/4HANA, adapted to the new data model. Ideally, data cleansing takes place in the legacy system, such as SAP ERP or a separate solution, ideally before data migration to the SAP S/4HANA system.
