Upgrade the PAN-OS Software Version Using Panorama

1. After upgrading Panorama, commit and push the configuration to the firewalls you are planning to upgrade.
2. Verify that enough hardware resources are available to the VM-Series firewall.
   Refer to the VM-Series System Requirements to see the resource requirements for each VM-Series model. Allocate additional hardware resources before continuing the upgrade process; the process for assigning additional hardware resources differs on each hypervisor.

   If the VM-Series firewall does not have the required resources for the model, it defaults to the capacity associated with the VM-50.
3. From the web interface, navigate to DeviceLicenses and make sure you have the correct VM-Series firewall license and that the license is activated.
   On the VM-Series firewall standalone version, navigate to DeviceSupport and make sure that you have activated the support license.
4. Save a backup of the current configuration file on each managed firewall you plan to upgrade.
   Although the firewall automatically creates a configuration backup, it is a best practice to create and externally store a backup before you upgrade.
   1. From the Panorama web interface, select PanoramaSetupOperations and click Export Panorama and devices config bundle to generate and export the latest configuration backup of Panorama and of each managed appliance.
   2. 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.
5. Update the content release version on the firewalls you plan to upgrade.
   Refer to the Release Notes for the minimum content release version required for PAN-OS 9.1. Make sure to follow the Best Practices for Application and Threat Updates when deploying content updates to Panorama and managed firewalls.
   1. Select PanoramaDevice DeploymentDynamic Updates and Check Now for the latest updates. If an update is available, the Action column displays a Download link.
   2. If not already installed, Download the latest content release version.
   3. Click Install, select the firewalls on which you want to install the update, and click OK. If you are upgrading HA firewalls, you must update content on both peers.
6. (HA firewall upgrades only) If you will be upgrading firewalls that are part of an HA pair, disable preemption. You need only disable this setting on one firewall in each HA pair.
   1. Select DeviceHigh Availability and edit the Election Settings.
   2. If enabled, disable (clear) the Preemptive setting and click OK.
   3. Commit your change. Make sure the commit is successful before you proceed with the upgrade.
7. Download the target PAN-OS release image.
   1. Select PanoramaDevice DeploymentSoftware and Check Now for the latest release versions.
   2. Download the firewall-specific file (or files) for the release version to which you are upgrading. You must download a separate installation file for each firewall model (or firewall series) that you intend to upgrade.
8. Install the PAN-OS software update on the firewalls.
   1. Click Install in the Action column that corresponds to the firewall models you want to upgrade.
   2. In the Deploy Software file dialog, select all firewalls that you want to upgrade. To reduce downtime, select only one peer in each HA pair. For active/passive pairs, select the passive peer; for active/active pairs, select the active-secondary peer.
   3. (HA firewall upgrades only) Make sure Group HA Peers is not selected.
   4. Select Reboot device after install.
   5. To begin the upgrade, click OK.
   6. 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 Reboot Device.
   7. After the firewalls finish rebooting, select PanoramaManaged Devices and verify the Software Version is 9.1.0 for the firewalls you upgraded. Also verify that the HA status of any passive firewalls you upgraded is still passive.
9. (HA firewall upgrades only) Upgrade the second HA peer in each HA pair.
   1. (Active/passive upgrades only) Suspend the active device in each active/passive pair you are upgrading.
      1. Switch context to the active firewall.
      2. In the High Availability widget on the Dashboard, verify that Local firewall state is Active and the Peer is Passive).
      3. Select DeviceHigh AvailabilityOperational CommandsSuspend local device.
      4. Go back to the High Availability widget on the Dashboard and verify that Local changed to Passive and Peer changed to Active.
   2. Go back to the Panorama context and select PanoramaDevice DeploymentSoftware.
   3. Click Install in the Action column that corresponds to the firewall models of the HA pairs you are upgrading.
   4. In the Deploy Software file dialog, select all firewalls that you want to upgrade. This time, select only the peers of the HA firewalls you just upgraded.
   5. Make sure Group HA Peers is not selected.
   6. Select Reboot device after install.
   7. To begin the upgrade, click OK.
   8. 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 Reboot Device.
   9. (Active/passive upgrades only) From the CLI of the peer you just upgraded, run the following command to make the firewall functional again:
      request high-availability state functional
10. (PAN-OS XFR upgrade only) Upgrade the first peer and second peer to PAN-OS XFR by repeating Step 8 and Step 9.
11. Verify the software and content release version running on each managed firewall.
    1. On Panorama, select PanoramaManaged Devices.
    2. Locate the firewalls and review the content and software versions in the table.
       For HA firewalls, you can also verify that the HA Status of each peer is as expected.
12. (HA firewall upgrades only) If you disabled preemption on one of your HA firewalls before you upgraded, then edit the Election Settings (DeviceHigh Availability) and re-enable the Preemptive setting for that firewall and then Commit the change.
