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 to 6.1.X. The Barracuda NG Control Center can only manage NG Firewalls using the same or lower firmware version. You cannot 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.

Before you Begin

If you are using SSL Interception on your border firewall, you must add dlportal.barracudanetworks.com to the SSL Interception Domain Exceptions on the your NG Firewall > Virtual Servers > Assigned Services > Firewall > Security Policy page.

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, or newer, firmware version before updating the managed NG Firewalls.

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

Step 5. Migrate the Configuration Version of the Cluster

  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.
  6. Click Activate
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 (CONFIGURATION > Configuration Tree > Multi-Range> your range).
  2. Right-click on the range and select Lock.
  3. Right-click on the range and select Migrate Range.
  4. Select the new Release version.
  5. Click OK.
  6. Click Activate.
