System Conversion to SAP S/4HANA

Upgrade Your System, Retain Your Processes: Your Soft Transition to SAP S/4HANA

They say, “never change a running system”. But you know that your business will benefit from a move to the innovative and efficiency boosting SAP S/4HANA ERP. You also know that your existing SAP ERP system will no longer be supported by 2027. So how about an upgrade of your running system, but you don’t have to change your running processes?

A System Conversion, also called Brownfield Conversion, allows you to keep your well-known and tested routines while benefiting from the new possibilities and technologies of SAP S/4HANA. 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 a SAP S/4HANA Brownfield 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 customizations.
