From Odoo 18
Upgrade from Odoo 18
If you search upgrade Odoo 18 or Odoo 18 to 17 / 18 / 19, this page is the map: support status, every target we handle, and a realistic fixed-price band for each hop.
Still supported
Odoo 18 — official support ended (or ends) September 2027 (planned). Your instance keeps running, but security patches and community module fixes for this branch have stopped or are stopping. Full EOL calendar →
Pick your target version
Bands are for a typical self-hosted Community setup. Complexity (custom JS, POS/warehouse overrides, abandoned third-party apps) moves the number more than hop count. We quote one fixed price for the whole jump.
Why leave Odoo 18?
- Security: Odoo only patches its three newest majors. 18 is outside that window.
- Stack age: Old Python / PostgreSQL under 18 hit their own EOL and make hosting painful.
- Modules freeze: OCA and vendors stop shipping 18.0 bugfixes.
- The jump grows: every year you wait adds another version to the eventual upgrade.
