For the benefit of anyone else who was using a QuoVadis certificate for their GlobalProtect portals/gateways (or presumably decryption), the process of replacing that intermediate is surprisingly easy.
Just import the new intermediate certificate using exactly the same name as the old intermediate certificate and it simply gets replaced. Which suggests an improvement - a warning that you're replacing a certificate in use with the option to cancel. You can verify that the new certificate is in place with =openssl s_client -showcerts -connect ${ip}:443= (some of us old farts can't remember those incantations like we used to).
Probably blindingly obvious and too late, but someone might find it useful.
Oh! And this was with PanOS 9.0.x
