How to Install Odoo 16

Odoo 16 was released in October 2022 and introduced major improvements to the Knowledge base, website builder, and manufacturing module. While now two major versions behind the current Odoo 19, it remains in use at organizations that have not yet migrated. This guide covers installing Odoo 16, but we recommend evaluating Odoo 19 for any new project.

Legacy Version Notice

Odoo 16 is now considered a legacy version. While it still receives critical security patches, all active development has moved to Odoo 18 and 19. Key reasons to consider upgrading:

• The Owl frontend (introduced in Odoo 17) provides significantly better performance
• Many OCA community modules are dropping Odoo 16 support
• Python 3.8 and 3.9 are reaching end-of-life
• Odoo 19 includes three years of improvements in every module
