Some organizations—for example, those running earlier versions of SAP® software that have few elements. It can be reused in an SAP S/4HANA Cloud solution environment—may elect not to convert but instead opt for a “greenfield” installation that requires data migration from the old system into a completely new SAP S/4HANA environment. However, for many others, a “brownfield” conversion is a likely path:
- Brownfield – Upgrading live systems and reusing existing system elements selectively.
- Smart brownfield – Creating a shell copy of the leading system with existing implemented processes and performing SAP System Landscape Optimization (SLO) tool-based migration of a selected or the full data scope.
At the beginning of a project, we assess the current SAP system and the steps required, including whether to maintain existing databases or move to a new version. Taking a phased approach makes it possible to manage the conversion costs in line with planned budgets and timetables.
All organizations converting to SAP S/4 HANA Implementation services must comply with several technical and functional requirements. These include a dual-stack split, Unicode conversion, and SAP New General Ledger activation.
A brownfield conversion is migrating existing SAP ERP systems to a new SAP S/4HANA system. It includes migrating data, applications, and customizations from the SAP ERP system to the new SAP S/4HANA system.
The process involves several steps, including:
1. Preparing the environment and performing a technical health check
2. Analyzing the existing system and customizations
3. Identifying and assessing potential risks and challenges
4. Defining the scope and objectives of the conversion
5. Designing the target system and architecture
6. Performing data migration and integration
7. Testing the system and validating the results
8. Implementing the new system and go-live
9. Providing post-implementation support and ongoing maintenance.
