Upgrade WildFire Appliances in a Cluster

You can use the CLI to upgrade WildFire appliances enrolled in a cluster individually, or use Panorama to upgrade the cluster as a group.
Depending on the number of samples the WildFire appliance has analyzed and stored, the time required to upgrade the appliance software varies; this is because upgrading requires the migration of all malware samples and 14 days of benign samples. Allow 30 to 60 minutes for each WildFire appliance that you have used in a production environment.
  • All nodes in a cluster must run the same version of the operating system.
  • Panorama can manage WildFire appliances and appliance clusters running PAN-OS software versions 8.0.1 or later.
  • Ensure the devices are connected to a reliable power source. A loss of power during an upgrade can make the devices unusable.
Depending on your deployment, perform one of the following tasks to upgrade your WildFire cluster:
