Before migrating your Barracuda NG Firewall to 6.1.x, review the requirements and changes listed in the following sections. Some changes applied during the migration might require you to make preparations before the update or extra configurations after the update.
Migration Path to 6.1.x
You can upgrade to firmware 6.1 from the following firmware versions:
|Current Version||Target Version|
|6.0.5 and higher||No||No||No||No|
- Direct updating from versions 4.2.x or 5.x to version 6.1.x is not possible.
- Barracuda NG Firewall F100 and F101 models must follow special migration instructions. See F100.
- The migration path for Barracuda NG Firewalls or NG Control Centers using Citrix Xen HVM images is 5.4 > 6.0.2 > 6.1.1 (or higher).
For more information on migrating to 6.0, see Migrating from 5.4.x to 6.0.x.

Legacy and Standard Hardware Systems
| Legacy |
Legacy phion appliances are not supported for version 6.x or higher.
| Standard Hardware |
A standard hardware system is a Barracuda NG Firewall running on 3rd party server hardware using an SF license. Consult the Barracuda Networks Technical Support in order to find out if your specific standard hardware is supported.
Disk Space Requirements
You must have at least 50 MB of free space in the /boot/ partition and twice the size of the update package in the / (root) partition.
Barracuda NG Firewall F100 / F101
The Barracuda NG Firewall F100 and F101 added support for virus scanning in the firewall for firmware 6.1.0 and higher. To improve performance and conserve disk space, the following additional changes were made:
- Avira is used as the virus scanner engine for the F100/F101. The ClamAV virus scanning engine is no longer available.
Complete the following steps to verify whether enough disk space is available:
If you do not have at least twice the size of the update package disk space available, complete the following steps before updating:
- Block the Virus Scanner service.
On the command line, delete unnecessary files by executing the following commands:
rm -rf /var/phion/mcdownload/clam/files/* rm -rf /var/phion/mcdownload/avira/files/* rm -rf /var/phion/preserve/boxupdate/updateStatus.db rm -rf /var/phion/preserve/boxupdate/clam/*
Upgrade Barracuda NG Control Center C400 / C610
If you are updating by reinstalling via a USB stick, change the boot device order in the BIOS. Contact Barracuda Networks Technical Support if you need the BIOS password.
Upgrading a High Availability (HA) Unit without Upgrading its HA Partner Unit
If you are upgrading a unit in a high availability (HA) cluster without upgrading its partner, you must re-synchronize both units:
- Go to the FIREWALL > Live > Show Proc page.
- Select the Sync Handler process and select Kill Selected.
The process is automatically restarted after a couple of seconds, and the primary and secondary unit automatically synchronize their sessions.
Barracuda NG Admin
After updating a system, you must also download the Barracuda NG Admin with the same version. Barracuda NG Admin is backward-compatible. This means you can manage 5.x NG Firewalls and NG Control Centers with Barracuda NG Admin 6.1.3.
Migration Instructions for 6.1.3
When upgrading from 6.0.x to 6.1.3, you must complete the migration steps listed below and also perform the migration steps for 6.1.0, 6.1.1, and 6.1.2 to complete the upgrade:
Secure Web Proxy
- The Secure Web Proxy is no longer supported with firmware version 6.1.3. Remove the service before updating to 6.1.3. Use SSL Interception and URL Filtering in the Firewall or HTTP Proxy instead.
For more information, see How to Configure SSL Interception in the Firewall, URL Filtering in the Firewall, or How to Set Up and Configure the HTTP Proxy.
Migration Instructions for 6.1.2
When upgrading from 6.0.x to 6.1.2, you must complete the migration steps for 6.1.0 and 6.1.3 listed below and also perform the migration steps for 6.1.1 to complete the upgrade:
- Remove /phion0/run/sshprx/YOUR_VIRTUAL_SERVER_YOUR_SSH_PROXY_SERVICE_NAME/USERNAME_ssh_config for the SSH proxy configuration to be modified to use the new ciphers added to the SSH Proxy service in 6.1.2.
Migration Instructions for 6.1.1
When upgrading from 6.0.x to 6.1.1, you must complete the migration steps for 6.1.0 listed below and also perform the migration steps for 6.1.1 to complete the upgrade:
NG Firewall and NG Control Center Firmware Update Element
- Add the IP addresses for the Barracuda Download portal (22.214.171.124 and 126.96.36.199 ) to the Barracuda Update Servers network object on the Barracuda NG Control Center and stand-alone NG Firewalls.
Citrix HVM Images
- Barracuda NG Firewalls and NG Control Centers running on a Citrix hypervisor using the HVM images now use the xen-netfront network driver instead of the 8139cp driver. Upgrade your Citrix XenServer to version 6.2 or higher to take advantage of the PVHVM support.
- Updating to 6.1.1 replaces your existing SSH key on the Barracuda OS level. Go to CONFIGURATION > Configuration Tree > Box > Identity and generate a new SSH Private Key for the SSH key in NG Admin and the SSH key on the box level to match up.
- Go to CONTROL > File Updates page, select Product Tips from the drop-down list, and click Set Area Config. Do a dummy change to active the configuration. This will enable or disable Product Tips for the NG Control Center and all its managed NG Firewalls.
Migration Instructions for 6.0.x to 6.1.0When upgrading from 6.0.x to 6.1.0, you must complete the following migration steps to complete the upgrade:
Managed NG Firewalls
- You must install Hotfixes 670 and 681 on the NG Control Center running 6.0.X before upgrading managed NG Firewalls to 6.1.
Barracuda NG Firewall F100 and F101 Virus Scanning Changes
To improve performance, Barracuda Networks recommends to use virus scanning in the firewall instead of malware scanning in the HTTP Proxy.
The ClamAV virus scanning engine is no longer available for F100/F101 - the Avira virus scanning engine is automatically started as a replacement. Go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Virus Scanner > Virus Scanner Settings to configure the Avira virus scanning engine settings.
- A dummy change to the Access Lists in the Filter Setup IPv4 and IPv6 of the CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > OSPF/RIP/BGP Settings page is required after the update for changes to the access lists order to take effect.
- All Route Maps in the Filter Setup IPv4 and IPv6 of the CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > OSPF/RIP/BGP Settings page must be deleted and, after a Send Changes and Activate, re-entered.
- Existing Outlook Web Access configurations are automatically migrated to use the new OWA 2007 Web Forward Template. If you are using OWA 2003 or 2010, go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > VPN > SSL VPN, edit the Outlook Web Access Web Forward, and select the correct OWA version from the Web Forward Template drop-down list.
- The default Event configuration has been improved for firmware 6.1.0. A new notification type was added. Events using the default settings are automatically migrated to the new default values. Events with non-default settings are not changed. For more information, see Events.
Step 3. Start the Update
Now you can update the Barracuda NG Firewall or Barracuda NG Control Center.
