### Database Migration

The `key` columns renaming migration is handled automatically, but if you have custom database scripts:

1. Update the `analytic`, `chatflow_starter_template`, `chatflow_template`, `user_template_response`, and `i18n_label` table `key` column to the new name
2. Review and test any custom queries
3. Update backup and maintenance scripts
