What do you do with the left behind applications?​

During a migration, organizations must assess their data and content in existing systems and decide what should be brought over and what can be purged or left behind. In any case, during a system upgrade, organizations are left with legacy applications that take up resources to maintain the data for compliance purposes, for example. ​

Sigma’s proprietary solution, the Sigma Migration Center (SMC) enables decommissioning of legacy SAP applications and optimizes for database growth in the new S/4HANA environment, making it leaner, more performant, and with less cost. Decommissioning with Sigma allows for the legacy data to still be accessible in the S/4HANA environment while optimizing the new environment’s data footprint. There is no dependency on originating application, so once the system is archived, it can be completely decommissioned, saving the organization on storage, maintenance, and hardware costs. ​

It is worth noting that a greenfield implementation is recommended by SAP because it can be done either on-premise or in the cloud and allows users to pre-define migration objects. From a cost standpoint, greenfield implementations result in lower total-cost-of-ownership (TCO) and time-to-value of the new S/4HANA system.
