Hi, I'm trying to make a change to a field in post installation, but despite having followed the guide (\https://odoo-development.readthedocs.io/en/latest/maintenance/data-migration.html), the file is not even read by odoo when I update the module. Is it possible that version 13 doesn't work anymore?
Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
- CRM
- e-Commerce
- Accounting
- Inventory
- PoS
- Project management
- MRP

Ok, I understand, the guide is not clear, you have to change the version of the addons from the __manifest__ and then upgrade the addons
