Retrieve your license API key from the Customer
Support Portal and install it using the CLI on the firewall and
Panorama. You must have superuser privileges on the firewall or
Panorama to install the license API key. When you install a license
API key on Panorama, Panorama pushes the API key to its managed
devices. If the managed device has an API key installed, Panorama
overwrites the old API key with the new one.
