PAN-OS Upgrade and Downgrade Behavior
When you upgrade an enforcement point to PAN-OS 12.2 or later release
and activate the Advanced IP Defense license, the Advanced IP Defense
configuration becomes available. When you downgrade the enforcement point below PAN-OS 12.2, the system automatically removes the Advanced IP Defense configuration. The license remains active, and the
configuration becomes available again when you upgrade back to PAN-OS
12.2 or later release.
Adding new IP attribute categories or tags to Advanced IP Defense does not
require a PAN-OS upgrade. Content updates deliver new attributes, and
they become available on the enforcement point after you install the update.
