Odoo 19 vs Odoo 20: Should You Upgrade?
What changed for businesses, what was removed, and who should upgrade now. Written by an Odoo Ready Partner that already runs four of its own products on Odoo 20.
Updated October 2026
The short answer
- On Odoo 17 or older: plan your upgrade now. Odoo fixes bugs for its three most recent major versions, and with Odoo 20 out, that is 18, 19 and 20.
- On Odoo 18 or 19: you have time. Upgrade in a quiet month, after you check the changes below against how you use Odoo.
- New to Odoo: start on Odoo 20.
Some of what follows is in Odoo Enterprise apps, such as Planning, Sign and Studio. If you run Odoo Community, the core changes still apply to you.
