The quality of the result depends on the foresight of the preceding, strategic considerations. Is the focus on a quick conversion or on the leanest possible result? Many things can be calculated better if thoughts are already spent on the "Beyond" before the conversion.
Simplifications specified by SAP must be implemented as part of the brownfield conversion. In addition, it is strongly recommended to clean up superfluous legacy systems. Analyses are used to identify enhancements and modifications to the SAP standard that are no longer necessary. This ballast, which has accumulated over years or even decades - including developments, data or customizing that have become obsolete - is consistently eliminated. The remaining company-specific developments are adopted during the conversion to S/4HANA.
Archiving can also be used to remove obsolete master and transaction data that is no longer required.
After the transformation, the existing processes, functions and their customizing are put to the test. In CONSILIO's Beyond Brownfield approach, specialists perform process and system optimization afterwards. This makes the system even leaner and prepares it for future innovations in S/4HANA - clean Digital Core.
Thus, the brownfield approach is the right way for most companies.
