Migration from 8.0.1/8.0.2/8.0.3/8.0.4/8.0.5 to 8.0.6

  • Last updated on

This article assumes that you have already successfully upgraded to firmware version 8.0.1/8.0.2/8.0.3/8.0.4/8.0.5.

Before You Begin

Important Notes Before Migrating
Split Control Centers

If you are running split Control Centers (multiple Control Centers in a parent-to-child relation), you must perform a series of steps in order to use split Control Centers with a simplified configuration.

 

The following instructions contain 2 sequences, where the first sequence (Steps 1-2) must be done before upgrading to 8.0.6 and the second sequence (Steps 3-5) afterward!

The upgrade contains a new default rule set for the host firewall that contains all new settings for running a split CC with an optimized configuration procedure. If you have made changes to your host firewall rule set, you must create a backup of your individual rules before upgrading and then restore them after the upgrade.

Step 1. (optional)

If you have modified the host firewall rule set by adding individual rules, create a backup of all your individual rules on all Control Centers (parent and child).

Step 2.

Perform the upgrade to firmware 8.0.6. During the upgrade, the default rule set for the host firewall will be updated and include all entries for a split Control Center.

Step 3.

After upgrading to 8.0.6, perform these steps:

  1. Log into the child Control Center(s).
  2. Go to CONFIGURATION > Configuration Tree > Multi Range > Global Settings > CC Parameters > Split Control Center.
  3. Click Lock.
  4. Switch to Advanced Configuration Mode.
  5. For Parent Control Center IP, enter the box level IP of the parent Control Center.
  6. Click Send Changes / Activate.
Step 4.

Perform a Copy from Default for the host firewall rule set for every split Control Center (parent and child).

Step 5. (optional)

If you have created a backup of individual host firewall rules, restore the rules.

Proxy and URL Filters

If you are upgrading from firmware version 8.0.4 to 8.0.6 and Default Access Control Policies are allowed in CONFIGURATION > Configuration Tree > Box > Assigned Services > HTTP Proxy > HTTP Proxy Settings > Access Control > ACL Entries > your entry for URL Filter Categories , you must check the categories that could be empty.

In any case, it is recommended to reconfigure them. If the list is not empty, perform a dummy change and re-enter the number for Num Categorize Helpers, and then confirm with Send Changes / Activate.

Header Reordering for VLANs and DHCP Relay Agent

Important

If you are using xDSL links on a VLAN interface, or if you are using the DHCP-server service or DHCP relay agent on your firewall, perform the steps below before applying the update:

  1. Go to Configuration Tree > Box > Network.
  2. On the left side, click Virtual LANs.
  3. In the list, double-click the VLAN entry where the xDSL is attached to.
  4. Enable Header Reordering.
  5. Click OK and Send Changes/Activate.
  6. Go to CONTROL > Box and click Network in the left navigation bar to expand the menu.
  7. In the left navigation bar, click Activate new network configuration.
  8. Click Soft... to trigger a network activation.

After completing these steps, it is safe to install update 8.0.6.

Within the reboot from the firmware update, the Header Reordering setting will be applied to your VLAN interface.

If these steps are not done before the update, be aware of the following:

  • Your xDSL connection will no longer work after the update.
  • Your DHCP server will no longer work as expected for VLANs after the update.
  • Your DHCP relay agent will no longer work as expected.

For more information on the setting for header reordering, see also 8.0.6 Release Notes, paragraph "Usage of DHCP on a VLAN Interface".

Barracuda Firewall Admin

After updating a system, you must also download Firewall Admin with the same version. Firewall Admin is backward-compatible. That means you can manage 7.x and 8.x F-Series Firewalls and Control Centers with Firewall Admin 8.x.

Always use the latest version of Barracuda Firewall Admin.

Read the Release Notes, especially the Known Issues section, for the firmware version that you want to update to.

For more information, see 8.0.6 Release Notes.

Migration Instructions for 8.0.6

When upgrading according to the migration path above, you must complete the migration steps listed below:

Step 1. (optional) Remove Virtual WAN Configuration

This step is necessary only if you have configured a connection to Microsoft Azure Virtual WAN.

In the following steps, you must remove the whole configuration for Azure Virtual WAN connections and re-enter all fields after the migration.

It is recommended to save a copy of the edit fields for easing the input after the migration, e.g., by making a screenshot.
  1. Log into the CloudGen Firewall with Firewall Admin.
  2. Go to CONFIGURATION > Configuration Tree > Multi Range > your range > your cluster > Boxes > your Box > Advanced Configuration > Cloud Integration.
  3. Select Azure Virtual WAN in the left menu.
  4. Click Lock.
  5. In the Azure Virtual WAN Connections section, click the entry of your Virtual WAN and click x to remove it.
  6. Click Send Changes and Activate.
After the update, you must reconnect to Microsoft Azure Virtual WAN and re-enter the previously deleted configuration.
