50 Release and Migration Notes - Determine Your Update Scenario

Determine Your Update Scenario

As soon as a unit has been updated to firmware version 5.2.3 and, subsequently, any new features were configured

using Barracuda NG Admin 5.2.1 or 5.2.3, no configuration changes must be made anymore using versions of

Barracuda NG Admin prior to version 5.2! Doing so could destroy the configuration.

Always use Barracuda NG Admin 5.2.3 together with Barracuda NG Firewall 5.2.3.

Updating to Barracuda NG Firewall 5.2.3 is possible from firmware release version 5.0 and newer. Direct

updating from release versions prior to 5.0 is not possible. Update to 5.0 first.

To install Barracuda NG Control Center C400 or C610 appliances from the thumb drive, it is necessary to change the

boot device order within the BIOS. Therefore you will need the unit’s BIOS password. You can obtain that password

through the Barracuda Networks Technical support.

In case you are updating a HA synchronized unit to firmware release version 5.2.3 while not updating its secondary

unit as well, or vice versa, so that the units run on different firmware versions, it may be necessary to re-synchronize

the units after updating. To do so, click Firewall > Live > Show Proc, select the process named Sync Handler and

choose Kill Selected. Session synchronization will automatically re-appear subsequently.

In order to use Microsoft Exchange 2010 via SSL VPN after updating to Barracuda NG Firewall 5.2.3, it is necessary

to perform Activate at least once within the SSL VPN settings in Barracuda NG Admin to correctly apply the update

to the SSL VPN engine.

See Supported Hardware, page 49 to determine whether your Barracuda hardware qualifies for a supported

installation of or a supported update to Barracuda NG Firewall 5.2.3.

If you are going to update so-called "standard hardware" from a firmware version prior to 5.0, please follow the

instructions given in Updating Standard Hardware from 4.2.x to 5.2.3, page 58.
