Odoo Database Migration: Module Not Installing After Upgrade

Question

After upgrading my Odoo instance, a custom module isn’t installing, and I get dependency errors. How do I resolve this?

Problem

When upgrading Odoo (e.g., from 14 to 16), custom modules can fail due to missing dependencies, API changes, or renamed fields.

Solution

• Check __manifest__.py for outdated dependencies.
• Run odoo-bin -u all --stop-after-init to force module updates.
• Inspect logs for missing fields and update your migration scripts.
• If necessary, remove orphaned database records manually: sql

DELETE FROM ir_model_data WHERE module = 'your_module' AND name = 'old_field';

• Finally, restart Odoo and reinstall the module.
