Upgrade the Firewall to PAN-OS 9.0

Determine the upgrade path and upgrade your standalone, HA, and Panorama-managed firewalls to PAN-OS 9.0.
How you upgrade to PAN-OS 9.0 depends on whether you have standalone firewalls or firewalls in a high availability (HA) configuration and, for either scenario, whether you use Panorama to manage your firewalls. Review the PAN-OS 9.0 Release Notes and then follow the procedure specific to your deployment:
When upgrading firewalls that you manage with Panorama or firewalls that are configured to forward content to a WildFire appliance, you must first upgrade Panorama and its Log Collectors and then upgrade the WildFire appliance before you upgrade the firewalls.
