Upgrade the Firewall to PAN-OS 9.1
Upgrade options for PAN-OS 9.1.
How you upgrade to PAN-OS 9.1 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 9.1
Release Notes and then follow the procedure specific to your deployment:
Additionally, it is not recommended
to manage firewalls running a later maintenance release than Panorama
as this may result in features not working as expected. For example,
it is not recommended to manage firewalls running PAN-OS 9.1.1 or
later maintenance releases if Panorama is running PAN-OS 9.1.0.
