Please Read Before Updating
Before installing any firmware version, be sure to make a backup of your configuration and read all release notes that apply to versions
more recent than the one currently running on your system.
Do not manually reboot your system at any time during an upgrade, unless otherwise instructed by Barracuda Networks Technical
Support. The update process typically takes only a few minutes after the update is applied. The appliance web interface for the
administrator will usually be available a minute or two before the SSL VPN user interface. If the process takes longer, please contact
Technical Support for further assistance.
