Hi All,
We have an on-premise installation of Odoo V18.
How we can upgrade the v18 version database to the v19 ?
Is it possible to do this on our part (together with the technical team) or are we obligated to send the database to Odoo, as described in the documentation.
Hi,
Upgrading an on-premise Odoo 18 database to Odoo 19 is possible, but it follows a specific process. Odoo treats database upgrades as part of its migration service. According to the official documentation, upgrades are normally handled by Odoo SA—you upload your database to their upgrade platform, and they return the migrated version. This ensures that all core modules and accounting rules are updated correctly.
For on-premise users, you can’t fully perform the database upgrade yourself. However, your technical team can prepare and test the migration process. The main steps are:
Prepare your current Odoo 18 database
Make sure it is clean: close open transactions, fix errors, uninstall unused or broken modules.
Back up your database and filestore.
Submit the database to Odoo’s Upgrade Service
Upload the dump of your Odoo 18 database through the official upgrade platform.
Odoo will process it and return a database compatible with Odoo 19.
Handle custom modules
Odoo only migrates the standard code. Your technical team must adapt and migrate custom apps/modules to ensure compatibility with v19.
This usually requires code refactoring and testing on a staging server.
Test the upgraded database
Restore the upgraded database in a staging environment running Odoo 19.
Verify all workflows, customizations, and integrations.
Go live
Once testing is validated, back up production again.
Restore the migrated database into your Odoo 19 instance and switch users to the new system.
The database upgrade itself must go through Odoo’s upgrade service, but your team is responsible for preparing the v18 database, adapting custom modules, and testing everything before go-live.
Hope it helps
Hi,
Thanks for the reply.
What about time - while Odoo is updating a copy of the database, business continues, and after creating a backup copy of the database and sending it to Odoo, there will be many transactions logged in the current working version, how can we manage them? sometimes it is almost impossible to use the export/import functions. How long will Odoo update my database?
We will start testing the upgrade of Odoo Online databases in October. If all goes well, we will then allow On Premise and Odoo.sh databases to be upgraded in November.
It could be earlier or later - we want to provide a smooth experience - so will adjust based on how well the first several thousand upgrades go.
Databases need to be sent to the Odoo migration service.
Hi Ray,
Thank you for prompt answer.
Just for to be fully clear:
1. As a partner or client, we have no other options for updating on our part, except to send the database to the Odoo migration service, am I right?
2. And my next question is: for what reason did you not provide the migration script to the end client or partner for self-processing?
I have asked your new Account Manager to reach out to you to discuss this in more detail.
Hi Ray,
Thank you, I will be waiting for the response from the customer service manager.
