What is the SAP brownfield approach?
The SAP brownfield approach means that you migrate your existing SAP system to SAP S/4HANA without having to rebuild everything. Your data, processes and custom code are retained and technically adapted.
In short: you keep your old system, but bring it up to date technically and functionally.
What is the SAP Greenfield approach?
The SAP Greenfield approach means that you build a new SAP S/4HANA system from scratch. Old processes and data are not transferred - only what you really need.
In short: you start from scratch, using best practices and state-of-the-art SAP processes.
