## Version History

- **1.0.0** (2024-11-25): Initial release with 5-star rating system

## Migration Guide

### From Standard Odoo Rating (0-3) to Five Stars (0-5)

The module automatically migrates existing ratings during installation:

1. **Backup your database** before installation
2. Install the module from Apps menu
3. Migration runs automatically on installation
4. Verify migration completed successfully in logs
5. Test rating functionality in a few tickets

**Migration Mapping:**
- 0 (No rating) → 0 (No rating)
- 1 (Unhappy 😞) → 3 (Average ⭐⭐⭐)
- 2 (Okay 😐) → 4 (Good ⭐⭐⭐⭐)
- 3 (Happy 😊) → 5 (Excellent ⭐⭐⭐⭐⭐)

**Rollback:**
If you need to rollback, uninstall the module. Note that ratings will remain in the 0-5 scale and will need manual conversion back to 0-3 if required.
