What are the implications of rolling back Django migrations?

Rolling back Django migrations can lead to data loss, schema inconsistencies, and potential application errors. It's important to understand the state of your database before proceeding.

Can you explain what data loss might occur?

Data loss can occur if you have added new fields or modified existing ones. Rolling back might remove these changes, leading to the loss of any data stored in those fields.

Are there any best practices to follow before rolling back?

Yes, always back up your database before rolling back migrations. Additionally, review the migration history and test the rollback in a staging environment first.

What if I need to roll back multiple migrations?

You can specify the migration to roll back to using the command python manage.py migrate app_name migration_name. Just be cautious of the implications for your data.
