Which statement about downgrading after an upgrade is true?

• A. There is no simple UI downgrade and Atlassian does not provide a rollback tool
• B. There is a built-in downgrade in the UI
• C. You can rollback using a plugin
• D. Downgrading is automatic

Answer: (A)

Downgrading after an upgrade isn’t supported. Atlassian does not provide a simple downgrade option in the UI or a rollback tool, because upgrades can change database schemas, indexes, and internal configurations in ways that aren’t safely reversible with a low-effort switch. The recommended way to revert to a previous version is to restore from a pre-upgrade backup: reinstall the older version, restore the application data and database from the backup, and then reconfigure as needed (including any necessary reindexing). This is why there isn’t a built-in UI downgrade, no plugin-supported rollback, and downgrading isn’t automatic.
