Free checklist
10 things to check before you upgrade to Odoo 20
An upgrade rarely fails because of Odoo. It fails because of the module from 2021, the interface nobody remembers anymore, and the fiscal position that Odoo 20 no longer allows. This checklist walks through the ten points we check first in every upgrade project.
Compiled from the official Odoo 20 release notes and our own upgrade projects. As of 30 September 2026.
