SAP ERP 6.0 (ECC), the core of SAP Business Suite 7, whose mainstream maintenance ends in 2027. Pages here cover midsize SAP ECC users weighing self-hosted Odoo against a move to SAP S/4HANA.
SAP ECC mainstream maintenance ends December 31, 2027, with paid extended maintenance to 2030. For midsize SAP ECC users: the options SAP offers, what a greenfield move to self-hosted Odoo involves instead, and the company profiles where that is realistic and where it is not.
SAP's support agreements for third-party databases and NetWeaver Java end with 2030, and conversion to S/4HANA from those systems is only possible before then. This page explains the deadline and compares a conversion, a greenfield S/4HANA project and leaving SAP for Odoo.
Comparing SAP ECC with Odoo for midsize companies replacing ECC: finance, controlling, materials management, sales and distribution and production planning against Odoo apps, ABAP custom code against Odoo modules, editions, and who supports Odoo on your own servers.
A greenfield move from SAP ECC to Odoo: scoping which processes and custom developments to keep, extracting masters and open items, mapping company codes, cost centers and plants to Odoo companies, analytic accounts and warehouses, and phasing the cutover.
Cost of ownership by component: SAP maintenance fees and the extended maintenance premium, an S/4HANA conversion or greenfield project, against Odoo Community or Enterprise on your own infrastructure, implementation, data migration and the internal team each path needs.
