Enterprises are re-evaluating their ERP and HR software stacks as SAP prepares to end mainstream maintenance for ECC 6.0 in December 2027. This transition is driving competition between major vendors, with SAP S/4HANA maintaining a lead in highly regulated manufacturing sectors, while Oracle Fusion Cloud ERP positions itself as a cloud-native alternative for discrete and mixed-mode manufacturers.

As maintenance deadlines approach, organizations face risks such as increased operating costs and security vulnerabilities if they delay migration to S/4HANA. While extended support is available until 2030, the end of mainstream maintenance for SAP Solution Manager 7.2 on December 31, 2027, is also prompting a shift toward SAP Cloud ALM. Companies must navigate these timelines carefully, as the availability of extended maintenance is tied to SAP Business Suite 7.
