Odoo upgrades

Version-specific Odoo upgrade pages: the Enterprise upgrade service, OpenUpgrade for Community, custom module porting and the support windows that set deadlines.

Odoo 17 to 18 upgrade

Upgrading from Odoo 17, whose standard support ended in September 2026, to 18.0: test database requests, custom module porting, neutralized testing, filestore merge and why some teams jump straight to 19 or 20 instead.

Odoo 18 to 19 upgrade

Moving from Odoo 18 to 19 before 18 leaves standard support in September 2027: PostgreSQL 13 minimum, the fiscal position tax mapping change, the new JSON-2 external API for integrations, and module porting and testing.

Odoo 19 to 20 upgrade

Planning the upgrade to Odoo 20, released September 2026: the mail tracking rework, expense flow changes, custom module porting, an upgraded test database and a rehearsal before cutting over production.

Odoo Community upgrades with OpenUpgrade

Upgrading Odoo Community without the Enterprise upgrade service: how OpenUpgrade migrates one major version at a time, module coverage checks, OCA module ports, test runs and when switching to Enterprise is the cheaper path.
