SAP S/4HANA is an inevitable change for SAP’s customers currently on ECC 6. However, SAP UK&I User Group reported that “70% of members don’t believe that SAP has been clear in communicating the migration path to S/4HANA”. Julien Delvat’s white paper helps clients face this change head on.

"S/4HANA is SAP’s next-generation Enterprise Resource Planning (ERP) Suite. Organizations planning to implement this real-time digital core to their business need to choose between a migration (brownfield) or start anew (greenfield). Bluefin Solutions outlines the pros and cons of each strategy and extends the choice with a hybrid solution."
