Release Notes Version

  • Last updated on

Before installing any firmware version, back up your configuration and read all release notes that apply to versions more recent than the one currently running on your system.

Before upgrading a virtual machine instance, take a snapshot. In the unlikely event that there is a problem with the kernel, you could use the snapshot to revert and attempt the upgrade again.

Do not manually reboot your system at any time during an update unless otherwise instructed by Barracuda Networks Technical Support. Depending on your current firmware version and other system factors, updating can take 10 to 20 minutes (updates which include a kernel upgrade take longer). If the process takes much longer than 20 minutes, contact Barracuda Networks Technical Support for assistance.
