How to Update Barracuda NG Control Center Managed Systems

  • Last updated on

The Barracuda NG Control Center can manage multiple clusters each using different firmware versions: 4.2.X, 5.0.X, 5.2.X, 5.4.X or 6.0.X. The Barracuda NG Control Center can only manage NG Firewalls using the same or lower firmware version. You can not mix different firmware versions in a cluster. When upgrading to new firmware versions you must first update  the NG Control Center then all NG Firewalls, virtual servers and services in the cluster at the same time. After all managed NG Firewalls in a cluster have been updated you must also migrate the cluster to the new release version.

In this article:

Step 1: Verify the Compatibility of Barracuda NG Control Center Versions with their Managed Units

The following table shows compatibility between the major versions of the Barracuda NG Control Center and various systems. Upgrade the Barracuda NG Control Center to the same firmware version, or newer before updating the managed NG Firewalls.

For more information, see Updating Barracuda NG Firewalls and NG Control Centers

Step 2: Import the Update Package into the Barracuda NG Control Center

Upload the update to the NG Control Center.

  1. Log into the Barracuda NG Control Center.
  2. Go to the Firmware Update page (Control > Firmware Update).
  3. Click Import and select the update package from the file browser.

The file is copied to the NG Control Center and displayed in the Files section.

Step 3: Send the Update Package to the Systems

  1. On the Firmware Update page, select the Ranges, Clusters, or Boxes to updated.
  2. In the Files section, select the imported update package.

  3. Select the systems which have received the entire update package and right-click the system select Perform Update.
  4. In the Schedule Task window, select Immediate Execution from the Scheduling Mode list and click OK.

Wait for the update to finish. Depending on the system hardware, the process can last anywhere from 15 minutes (for a fast system) to 60 minutes (for flash appliances).

Unless noted otherwise all Barracuda NG Firewalls will reboot after the update has been applied.

Step 5. Migrate the Configuration Version of the Cluster

If you are updating to a new major version (5.2 to 5.4 or 5.4. to 6.0) you must migrate the cluster version after the update has completed.

  2. Right click on the cluster and select Lock.
  3. Right click on the cluster and select Migrate Cluster.
  4. Select the new Release version.
  5. Click OK.

Update all the Clusters in a Range

If all clusters in the range are on the same firmware version you can migrate all clusters simultaneously. 

  1. Open the range containing the clusters you just updated (Config > Config Tree > Multi-Range> your range).
  2. Right click on the range and select Lock.
  3. Right click on the range and select Migrate Range.
