Upgrade a WildFire Cluster from Panorama without an Internet Connection

WildFire appliances in a cluster can be upgraded in parallel when they are managed by Panorama. If Panorama does not have a direct connection to the internet, you must download the software content and updates from the Palo Alto Networks Support site and host them on an internal server before they can be distributed by Panorama.
Panorama can only manage WildFire appliances and appliance clusters operating the same software version or a later software version.
  1. Upgrade Panorama to an equal or later release than the target software release you want to install on the WildFire cluster.
    For information on upgrading Panorama, refer to Install Content and Software Updates for Panorama.
  2. Temporarily suspend sample analysis.
    1. Stop firewalls from forwarding any new samples to the WildFire appliance.
      1. Log in to the firewall web interface.
      2. Select
        Device > Setup > WildFire
        and edit
        General Settings
      3. Clear the
        WildFire Private Cloud
      4. Click
    2. Confirm that analysis for samples the firewalls already submitted to the appliance is complete:
      1. Log in to the Panorama web interface.
      2. Select
        Panorama > Managed WildFire Clusters
        the cluster analysis environment
      3. Verify that the
        Virtual Machine Usage
        does not show any sample analysis in progress.
      If you do not want to wait for the WildFire appliance to finish analyzing recently-submitted samples, you can continue to the next step. However, consider that the WildFire appliance then drops pending samples from the analysis queue.
  3. Download the WildFire content and software updates to a host that has internet access. Panorama must have access to the host.

      3. Click the filename and save the file to the host.

  5. Download the PAN-OS software version to the WildFire appliance.
