Determine the Upgrade Path to PAN-OS 8.0
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
(for example, to get from a 7.0 release version to 8.0, you would
also need to install a 7.1 release version). In most cases, the
recommended path when moving from one feature release to the next
is to download the base image for the next feature release version
and then download and install your target maintenance release version.
You must have both the base image and the maintenance release image
on the firewall for installation to be successful. If the firewall
doesn’t have enough disk space to hold both the base image and the
maintenance release image, it will delete the base image and you
will see an error message when you attempt to install the maintenance
release. In this case you will need to re-download and install the
base image before you can download and install the maintenance release.
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.
Determine the upgrade path as follows:
- Identify
which version is currently installed.
- From Panorama, select and check the Software Version on the firewalls you plan to upgrade.
- From the firewall, select and check which version has a check mark in the Currently Installed column.
- Identify the upgrade path:Review the known issues and changes to default behavior in the Release Notes and upgrade/downgrade considerations in the New Features Guide for each release through which you pass as part of your upgrade path.
