I am new on Paloalto and want to upgrade PAN OS. Like Cisco or Juniper, we can downloa New OS into USB drive then we can simply upgrade from USB.
I have searched PAN OS upgrade using USB but seems I can't find the proper guide.
Can someone advise if there is any doc?
PS: My PAN FW is not connected to internet so i can't download directly from PAN OS.
You can download the file to your local system. Then use the "Upload From File" option under Device tab --> Software to upload the file from your local system to the firewall.
Not 100% sure where to download the PanOS file from, but it should be doable.
Edit: ah, you download it from the PA Support Portal.
let's say my PAN FW is not connected to internet so i can't download the PAN OS into local system. But I can download the PAN OS on my laptop with USB. Then, I would like to insert the USB drive on PAN FW. I used to use upgrade JUNOS or Cisco that way but not sure if I can do on PNA OS.
You download it to your laptop while connected to your normal network.
Unplug your laptop and directly connect it to the firewall.
Login to the web interface on the firewall.
Device tab --> Software --> Upload.
Do the upgrade as per normal from there.
