Upgrade a Standalone Firewall to PAN-OS 8.0

Review the PAN-OS 8.0 Release Notes and then use the following procedure to upgrade a firewall not in an HA configuration to PAN-OS 8.0.
If your firewalls are configured to forward samples to a WF-500 appliance for analysis, you must upgrade the WildFire appliance to PAN-OS 8.0 before you upgrade the forwarding firewalls.
Ensure the firewall is connected to a reliable power source. A loss of power during an upgrade can make the firewall unusable.
  1. Save a backup of the current configuration file.
    Although the firewall automatically creates a configuration backup, it is a best practice to create and externally store a backup before you upgrade.
    1. Select DeviceSetupOperations and click Export named configuration snapshot.

    2. Select the XML file that contains your running configuration (for example, running-config.xml) and click OK to export the configuration file.

    3. Save the exported file to a location external to the firewall. You can use this backup to restore the configuration if you have problems with the upgrade.
  2. Ensure that the firewall is running the latest content release version. Refer to the Release Notes for the minimum content release version you must install for a PAN-OS 8.0 release. Make sure to follow the Best Practices for Application and Threat ContentUpdates
    1. Select DeviceDynamic Updates and check which Applications or Applications and Threats to determine which update is Currently Installed.

    2. If the firewall is not running the minimum required update or a later version, Check Now to retrieve a list of available updates.
    3. Locate and Download the content release version you intend to install. After you successfully download a content update file, the link in the Action column changes from Download to Install for that release version.
    4. Install the update.
  3. Determine the Upgrade Path to PAN-OS 8.0
    You cannot skip installation of any feature release versions in the path from the currently running PAN-OS version to PAN-OS 8.0.
    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.
  4. Upgrade to PAN-OS 8.0.
    If your firewall does not have internet access from the management port, you can download the software image from the PaloAltoNetworks Support Portal and then manually Upload it to your firewall.
    1. Select DeviceSoftware and click Check Now to display the latest PAN-OS updates.
    2. Locate and Download PAN-OS 8.0.0.
    3. After you download the image (or, for a manual upgrade, after you upload the image), Install the image.
      As a best practice, when upgrading to a PAN-OS 8.0 release, install the PAN-OS 8.0.0 base image and reboot the firewall before you download and install a PAN-OS 8.0 maintenance release.
    4. After the installation completes successfully, reboot using one of the following methods:
      • If you are prompted to reboot, click Yes.
      • If you are not prompted to reboot, select DeviceSetupOperations and click Reboot Device.
  5. Verify that the firewall is passing traffic.
    Select MonitorSession Browser.
