A Panorama™ management server running PAN-OS®
8.1 does not currently support management of appliances running WildFire
7.1 or earlier releases. Even though these management options are
visible on the Panorama 8.1 web interface (
Managed WildFire Clusters
Managed WildFire Appliances
making changes to these settings for appliances running WildFire
7.1 or an earlier release has no effect.
) You cannot send a commit from a Panorama appliance running a
PAN-OS 8.1 release to a WF-500 appliance running a PAN-OS 8.0 release
because the RADIUS authentication protocol is incorrectly changed
to CHAP authentication.
In rare cases when you upgrade a WF-500
appliance from a PAN-OS 7.1 release to a PAN-OS 8.0 release, the
disk partition becomes full due to the amount of data on the drive. When
you try deleting the backup database to free up space, the
fails and displays the following error:
Server error : Client wf_devsrvr not ready.

WildFire appliances build and release all
untested signatures to the connected firewalls every five minutes,
which is the maximum time that a signature remains untested (not released
to firewalls). When a WildFire appliance joins a cluster, if any
untested (unreleased) signatures are on the appliance, they may
be lost instead of migrating to the cluster, depending on when the
last build of untested signatures occurred.
