Downgrading to previous firmware versions

Downgrading to previous firmware versions results in configuration loss on all models. Only the following settings are retained:

• operation mode
• interface IP/management IP
• static route table
• DNS settings
• VDOM parameters/settings
• admin user account
• session helpers
• system access profiles

If you have long VDOM names, you must shorten the long VDOM names (maximum 11 characters) before downgrading:

1. Back up your configuration.
2. In the backup configuration, replace all long VDOM names with its corresponding short VDOM name.

   For example, replace edit <long_vdom_name>/<short_name> with edit <short_name>/<short_name>.

3. Restore the configuration.
4. Perform the downgrade.
