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.
