S/4HANA implementations typically assume one of two variants. Conversion: The conversion variant is characterised by basing the S/4HANA implementation on an existing SAP ECC system. Mapper IT mix of functional and technical expertise helps you plan and execute the upgrade and conversion process minimising disruption to the business and maximising the value you derive from S/4HANA. New System: The other variant is based on the implementation of the S/4HANA system from scratch. This variant is selected not only by new SAP customers, but also by some existing SAP customers who want to take the opportunity to re-baseline and ensure they achieve digital transformation and not be influenced by the previous system.
