Hold on to your company’s individual and well-established processes and access all historical data as well as your own developments in the new system.

What is the SAP S/4HANA Move (Brownfield SAP S/4HANA Conversion)?

Brownfield Conversion means that you migrate your data from an existing SAP Business Suite system to SAP S/4HANA. Your existing ERP system (e.g. SAP ECC) is upgraded to the new version of the Business Suite by performing a step by step conversion.

What you receive is a mix of accustomed features you’ve grown to like and new features that help you improve your business even further. Processes can be adapted to the SAP standard and with the launch of RISE with SAP, there is also the option of switching from an on-premise to a cloud-based SAP system in the course of a Brownfield Conversion.

This migration approach is best suited for companies that want to retain their previous invest, individualizations and customisations.
