While the S/4HANA Greenfield migration approach (see S/4HANA migration: Greenfield) involves a complete reimplementation of your SAP ERP system, the Brownfield approach represents more of a system upgrade in which the existing processes are adopted. One reason why S/4HANA Brownfield migrations are preferred over new implementations is the possible and individual division into different project phases. This allows you constant transparency with regard to the scope of the project and ongoing optimization of project management.

Goals and successes of an SAP S/4HANA migration in the Brownfield approach

A Brownfield migration to the new S/4HANA system offers many opportunities for companies:

  • Proven business processes can be easily adopted including adjustments.

  • At the same time there is the option to remove dysfunctional processes.

  • The project duration is shortened as part of the brownfield approach.

  • Historical data will continue to be used.

  • Existing elements such as interfaces to suppliers can be retained.

When is an S/4HANA Brownfield migration interesting?

Due to the complexity of the transformation, a Brownfield implementation preferably takes place on-premise. In this respect, the S/4HANA Brownfield migration approach is ideal for you if you want to continue using your current data and solutions and quickly switch from SAP ECC to SAP S/4HANA. The quality of your existing and adapted processes is crucial for the move. The procedure for a Brownfield migration usually takes place in two phases – the preparation and implementation phase. As part of the preparation phase (see SAP S/4HANA migration workshop), we check, among other things: Your process quality or the compatibility of your own developments.
