In a heterogenous software environment, SAP NetWeaver allows organizations to integrate data, business processes, and various elements from different sources into a unified SAP environment. Serving as the foundation on which SAP Business Suite 7 is based, and providing the architecture for enterprise application integration, it was necessary to fully align the maintenance strategy of SAP NetWeaver 7.5 with that of SAP Business Suite 7. As with SAP Business Suite 7, mainstream maintenance for SAP NetWeaver 7.5 is prolongated until the end of 2027, followed by an optional extended maintenance phase until the end of 2030. This extended maintenance phase for SAP NetWeaver 7.5 comes at the same price and conditions as those for SAP Business Suite 7. Mainstream maintenance for previous releases of SAP NetWeaver will expire at the end of 2020, as they are not suited for interoperability with SAP Business Suite 7 over the next decade.
