Determine the Upgrade Path to PAN-OS 9.1
Upgrade path planning for PAN-OS 9.1.
When you upgrade from one PAN-OS feature release
version to a later feature release, you cannot skip the installation
of any feature release versions in the path to your target release.
In addition, the recommended upgrade path includes installing the
latest maintenance release in each release version before you install the
base image for the next feature release version. To minimize downtime
for your users, perform upgrades during non-business hours.
For
manual upgrades, you must install the base image for a feature release before
you upload and install a maintenance release image.
