Odoo 15, released in October 2021, brought speed and usability work across sales and CRM, accounting, the website and eCommerce, manufacturing and HR, plus more predictive features. Its standard support ended in October 2024. Odoo's support table now shows both Odoo 14 and Odoo 15 as unsupported on Odoo Online, with paid extended support on Odoo.sh and on-premise that covers helpdesk and bug fixes but not security updates. If you are running either version, the practical comparison is no longer 14 against 15 but your database against a supported target — Odoo 17, 18 or Odoo 19.

Questions we get asked
Is Odoo 15 still supported?
Not under standard support. Odoo 15 was released in October 2021 and its three years of standard support ended in October 2024. Odoo's table now shows it as unsupported on Odoo Online, with paid extended support available on Odoo.sh and on-premise. Extended support carries a mandatory extra fee and covers helpdesk and bug fixes, not security updates.
Can I upgrade from Odoo 15 straight to Odoo 19?
Yes. Odoo accepts an upgrade from any version onto a supported target, and its upgrade platform currently lists 17.0, 18.0 and 19.0. There is no need to stop at 16 on the way. The standard data conversion runs as one request; custom and third-party modules must be available for the target version before the upgrade can complete.
How much will an Odoo 15 to Odoo 19 upgrade change for users?
Enough to need training. Four releases of interface work sit in between, the accounting and inventory screens have been reorganised, and Odoo 19 adds an AI app on Enterprise. Odoo's own advice is to have the people who use each app test an upgraded copy before go-live, precisely because view and workflow changes surprise users more than data problems do.
Is the upgrade free if I have an Enterprise subscription?
The upgrade service is. Odoo's SLA makes upgrading to the most recent version free for Enterprise subscribers, including help with discrepancies in the upgraded database, and it covers standard apps and Studio customisations. It does not cover in-house or third-party modules without a maintenance contract, cleaning up old data, or training. Community users have no access to that service.
Should I move off Odoo 15 now or wait?
Now. Odoo 15 already runs without security updates, and Odoo only upgrades onto supported versions, so the gap you have to close grows each year rather than shrinking. Going to Odoo 19 buys standard support into September 2028; going to 18 only reaches September 2027 for similar effort. Our upgrade guide sets out the steps.
