SAP S/4HANA Migration

Welcome to SAP knowledge in a nutshell. Do you need to migrate your SAP authorizations to S/4HANA, and you wanna know which project approaches exist and which one is the right one for you? In this video, we'll break down the three main s four handed transition approaches, Greenfield, Brownfield, and Bluefield, and explain how to figure out which one fits your company best. For new SAP customers, the greenfield approach is the only project method when moving from a non SAP system to implement SAP for the first time while aiming to establish a future proof and high performance authorization concept right from the start. Existing customers who want to migrate from SAP ERP to SAP S/4HANA can also choose the greenfield scenario. In this case, it is referred to as a reimplementation. A reimplementation is used when customers face the problem of an outdated, highly inconsistent system or when they want to redefine their business processes. In such a reimplementation, you can choose a complete redesign project approach where the entire authorization concept is reworked. However, in parallel to the redesign, a migration project must be carried out to adapt the existing roles to the new requirements, which increases complexity. A major disadvantage of the greenfield approach is the high effort involved in transferring data, authorizations, and business processes. However, it is also the best way to fully leverage all the advantages of S/4HANA from the start, completely in standard. The brownfield approach refers to the migration of an existing, well maintained, and standard compliant SAP ERP system to the new SAPS/4HANA release. The advantage of this method is that it can be implemented faster since the existing system does not need to be completely rebuilt. Instead, the existing business processes, data, and configurations are largely retained. The downside, however, is that existing legacy issues, outdated processes, and inefficiencies are also carried over into the new system. In such cases, additional redesign work may be required, sometimes even more than with greenfield. The blue field approach is a hybrid method that combines the advantages of greenfield and brownfield. This approach is most often used for transitioning multiple legacy systems into one consolidated SAP S/4 HANA system resulting in a full redesign of the current authorization concept. Here, only selected and particularly relevant data and processes are migrated. There is also the possibility to optimize certain business processes. In this way, the entire system does not need to be completely rebuilt or redesigned as in the greenfield approach, while at the same time avoiding unnecessary legacy issues that often come with a brownfield migration.
