Downgrade from Fireware XTM v11.3.x to v11.x
If you want to downgrade from Fireware XTM v11.3.x to an earlier version of Fireware XTM, you either:
- Restore a previously created full backup image to complete the downgrade; or
- Reset your Firebox or XTM device to its factory-default settings and then run the Quick Setup Wizard with the older version of Fireware XTM already installed on your management computer.
