How should I swap one Barracuda Spam & Virus Firewall on my network with another?

Solution #00002441

Scope:
All Barracuda Spam & Virus Firewalls, all firmware versions.

Answer:
If you want to swap out one Barracuda Spam & Virus Firewall for another seamlessly (with no interruption in email service), as in the case where you receive an RMA or replacement unit, please follow the steps below:
  1. Back up all of the old unit's configurations separately using the Advanced > Backup page, including System Configuration, User Settings, Valid Recipients (if available), and both Global and User Bayesian database backups if necessary.
  2. Connect the new Barracuda Spam & Virus Firewall to your network.
  3. Connect a monitor and keyboard to the Barracuda and configure the IP, Subnet, Gateway, and DNS settings (as per the Barracuda Spam & Virus Firewall Quick Start Guide).
  4. Log into the new Barracuda's web interface and update the Energize Updates (Advanced > Energize Updates) and firmware (Advanced > Firmware).
  5. Once the firmware version of the new Barracuda Spam & Virus Firewall matches or is newer than that of the Barracuda Spam & Virus Firewall being replaced, rename the backup files obtained in step 1 by replacing the serial number of the old Barracuda with the serial number of the new Barracuda. For example, if the old Barracuda's serial number is BAR-SF-22222 and the new Barracuda's serial number is BAR-SF-88888, the configuration backup file BAR-SF-22222-config.bak should become BAR-SF-88888-config.bak.
  6. Load the backup files, one by one, using the Restore Backup File feature on the Advanced > Backup page of the Barracuda's web interface. If you receive a checksum error, please see Solution #00001406.
  7. Direct all relevant network traffic away from the old Barracuda and to the new Barracuda.
  8. Shut down and remove the old Barracuda.
Alternatively, if you don't want to change any of your other network settings, you can remove your old Barracuda Spam & Virus Firewall, replace it with your new Barracuda Spam & Virus Firewall, and assign your old Barracuda Spam & Virus Firewall's IP address to your new Barracuda Spam & Virus Firewall. This could result in downtime during the switch because two devices cannot coexist on the same network with the same IP address.

Additional Notes:
If you are replacing a Barracuda Spam & Virus Firewallin a cluster, the recommended procedure is a little different. You do not need to create and restore backup files because the cluster will force a synchronization of all configuration settings. Follow these steps instead:
  1. From the web interface of any Barracuda Spam & Virus Firewall in your cluster, navigate to the Advanced > Clustering page and remove the Barracuda Spam & Virus Firewall to be replaced by clicking the trash can icon next to the IP address of that Barracuda Spam & Virus Firewall. Wait for the page to reload and verify on the other Barracuda Spam & Virus Firewalls in the cluster (by checking the Advanced > Clustering page) that it has been removed.
  2. Shut down and remove the old Barracuda.
  3. Connect the new Barracuda Spam & Virus Firewall to your network.
  4. Connect a monitor and keyboard to the Barracuda and configure the IP, Subnet, Gateway, and DNS settings (as per the Barracuda Spam & Virus Firewall Quick Start Guide), using the same IP information as the previous Barracuda Spam & Virus Firewall.
  5. Log into the new Barracuda's web interface and update the Energize Updates (Advanced > Energize Updates) and firmware (Advanced > Firmware).
  6. Once the firmware version of the new Barracuda Spam & Virus Firewall matches (exactly) that of the other Barracuda Spam & Virus Firewalls in the cluster, navigate to the Advanced > Clustering page of the new Barracuda Spam & Virus Firewall's web interface and join the cluster. This is done by entering the IP address of any of the existing Barracuda Spam & Virus Firewalls into the Clustered Systems section and clicking the Join Cluster button. Depending on the number of user quarantine accounts present on each Barracuda Spam & Virus Firewall in the cluster, the clustering process may take up to 24 hours.
