Consider an upgrade project when you see:
- You are two or more major versions behind current Odoo.
- Critical apps need features only available on a newer release.
- Custom modules block security or performance fixes.
- UAT and backups are mature enough for a controlled cutover.
- Business owners can commit a go-live window.
