I'll kick it off.
I will be updating the OS on my firewalls to a version that does not support the version of GP most of my users are running. Current version; PANOS 7.1.19, GP 3.1.1. I Plan to download GP 5.1.1 and use the "Install Transparent" option the get most of my users updated then update the FW to 8.1.13. My question is after i update the FW and a user with an older version of GP tries to connect will the client update of just fail to connect?
Minimum compatible version of GP app with PANOS 8.1.x is 4.0.
You could try older versions and it may also work in some cases but new features sets will not be available. But as you said, you have already enabled "allow transparently ", this setting will automatically upgrade the agent whenever a new version is available on the portal.
Hope it helps!
thank you for the reply. I have a case open with tac. I'm trying to confirm that the client will at least connect to update. I believe tac's answer is yes but it was a little obtuse.
