Since every company has individual requirements and ideas, there is no universal, correct way to migrate.
Greenfield
The first option is the greenfield approach - a completely new implementation of processes on SAP S/4HANA. This enables a complete redesign, as well as process simplification. Master data can be transferred, the potential of SAP S/HANA - such as new analysis options - is exploited from the outset, giving companies a high degree of flexibility for requirements and innovations in the future. If the choice falls on this migration approach, however, radical changes may be required:
The greenfield approach offers the decisive advantage that customers can analyze and optimize their processes. In addition, old processes can be made more efficient. However, when preparing for data migration, companies increasingly come across data that can no longer be migrated. In order to archive this data securely, there are several data archiving providers on the market. The new system may result in changes to business processes, requiring a redesign. Employees must adapt to the changes, which may also affect the IT department. To take full advantage of the capabilities and benefits of SAP S/4HANA, new skills are often required.

To take full advantage of the capabilities and benefits of SAP S/4HANA, new skills are often required. Due to the familiarization period, preceding analyses, a deep cleansing of the data and transformation of the business processes, companies must expect an increased expenditure of time with the greenfield approach.

Brownfield
The brownfield approach is a system conversion in which the existing SAP system is modified to SAP S/4HANA. Data, existing processes and in-house developments can thus be transferred to the new system. This means that less adaptation is required on the part of the company to SAP S/4HANA, but there is no exhaustion of the complex possibilities offered by the new system.

This approach can therefore be interesting for companies that are satisfied with their existing business processes and do not see an immense need for change. However, despite a time-saving process, the brownfield approach carries an increased risk of potential technical problems that can be labor-intensive to correct.

Hybrid
The hybrid approach resorts to a selective data switch and is to be located quasi between brownfield and greenfield.
- Lack of communication and planning can lead to failure to meet the actual business plan and goals
- Complex current IT landscapes
- Uncompleted and imprecise data backup
- Missing technical knowledge
The hybrid approach resorts to a selective data switch and is to be located quasi between brownfield and greenfield. This means that both the advantages and disadvantages of the two migration approaches already described are bundled. Due to the limited experience on the market to date, the hybrid approach has been considered risky. The selection of suitable tools must therefore be made with increased caution. An example for the Hybrid Approach in the main finance department can be found in our Whitepaper, which also provides further details about the transition to SAP S/4HANA.

With fewer legal forms and full use of the possibilities offered by SAP S/4HANA, a consolidated data landscape can be quite beneficial. In addition, the simpler and smaller architecture allows companies to create simpler, consistent processes and view master (data) consistently in real time. This is advantageous for decision makers, among others, data analyses are more efficient, faster, and more certain.
