Upgrade Firewalls When Panorama Is Not Internet-Connected

1. Log in to the Panorama web interface.
2. Modified your Security policy rule to allow ssl application traffic.

   This is required to prevent managed devices disconnecting from Panorama after upgrade to PAN-OS 10.2 if traffic between Panorama and managed devices is controlled using the panorama App-ID. Managed devices will disconnect from Panorama if the ssl application is not allowed before you upgrade.

   PAN-OS 10.2 uses TLS version 1.3 to encrypt the service certificate and handshake messages between Panorama and managed firewalls. As a result, the App-ID for traffic from managed firewalls to Panorama is reclassified from panorama to ssl. To continue communication between Panorama and managed devices, you must modify the Security policy rule controlling traffic between Panorama and managed devices to also allow the ssl application.

   Skip this step if the Security policy rule controlling traffic between Panorama and managed devices allows Any application or if you already modified your Security policy rule controlling traffic between Panorama and managed devices.

   1. Select PoliciesSecurityPre Rules.
   2. Select Device Group containing the Security policy rule controlling traffic between Panorama and managed firewalls.
   3. Select the Security policy rule.
   4. Select Application and Add the ssl.

      Do not delete the panorama application. This will cause all managed firewalls to disconnect from Panorama after you push the changes.

   5. Click OK.
   6. Select CommitCommit and Push and Commit and Push your configuration changes.
3. 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. Export Panorama and devices config bundle (PanoramaSetupOperations) 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.
4. Determine which content updates you need to install. Refer to Release Notes for the minimum content release version you must install for a PAN-OS® release.

   Palo Alto Networks highly recommends that Panorama, Log Collectors, and all managed firewalls run the same content release version.

   For each content update, determine whether you need updates and take note of which content updates you need to download in Step 5.

   Ensure that Panorama is running the same but not a later content release version than is running on managed firewalls and Log Collectors.
5. Determine the software upgrade path for the firewalls that you intend to update to Panorama 10.2.

   Log in to Panorama, select PanoramaManaged Devices, and note the current Software Version for the firewalls you intend to upgrade.

   You cannot skip installation of any feature release versions in the path from the currently running PAN-OS version to PAN-OS 10.2.0.

   Review PAN-OS Upgrade Checklist, the known issues and changes to default behavior in the Release Notes and Upgrade/Downgrade Considerations for each release through which you pass as part of your upgrade path.
6. Download the content and software updates to a host that can connect and upload the files to Panorama either over SCP or HTTPS.

   By default, you can upload a maximum of two software or content updates of each type to a Panorama appliance and if you download a third update of the same type, Panorama will delete the update for the earliest version of that type. If you need to upload more than two software updates or content updates of a single type, use the set max-num-images count <number> CLI command to increase the maximum number of images that Panorama can store.

   1. Use a host with internet access to log in to the Palo Alto Networks Customer Support web site.
   2. Download content updates:

      1. Click Dynamic Updates in the Resources section.
      2. Download the latest content release version (or, at a minimum, the same or a later version than you will install or is running on the Panorama management server) and save the file to the host; repeat for each content type you need to update.
   3. Download software updates:

      1. Return to the main page of the Palo Alto Networks Customer Support web site and click Software Updates in the Resources section.
      2. Review the Download column to determine which versions you need to install. The filename of the update packages indicates the model. For example, to upgrade a PA-220 and PA-5260 firewall to PAN-OS 10.2.0, download the PanOS_220-10.2.0, PanOS_3000-10.2.0, and PanOS_5200-10.2.0 images.
         You can quickly locate specific PAN-OS images by selecting PAN-OS for the PA-<series/model> from the Filter By drop-down.
   4. Click the appropriate filename and save the file to the host.
7. Install content updates on managed firewalls.

   You must install content updates before software updates.

   Install the Applications or Applications and Threats update first and then install any other updates (Antivirus, WildFire®, or URL Filtering) as needed, one at a time, and in any sequence.

   1. Select PanoramaDevice DeploymentDynamic Updates.
   2. Click Upload, select the update Type, Browse to the appropriate content update file, and click OK.
   3. Click Install From File, select the update Type, and select the File Name of the content update you just uploaded.
   4. Select the firewalls on which to install the update.
   5. Click OK to start the installation.
   6. Repeat these steps for each content update.
8. (Firewalls serving as GlobalProtect™ portals only) Upload and activate a GlobalProtect agent/app software update on firewalls.

   You activate the update on firewalls so that users can download it to their endpoints (client systems).

   1. Use a host with internet access to log in to the Palo Alto Networks Customer Support website.
   2. Download the appropriate GlobalProtect agent/app software update.
   3. On Panorama, select PanoramaDevice DeploymentGlobalProtect Client.
   4. Click Upload, Browse to the appropriate GlobalProtect agent/app software update on the host to which you downloaded the file, and click OK.
   5. Click Activate From File and select the File Name of the GlobalProtect agent/app update you just uploaded.

      You can activate only one version of agent/app software at a time. If you activate a new version but some agents require a previous version, you will have to reactivate the earlier version again for those agents to download the previous update.
   6. Select the firewalls on which to activate the update.
   7. Click OK to activate.
9. Upload PAN-OS software updates.

   1. Select PanoramaDevice DeploymentSoftware.
   2. Click Upload, Browse to the appropriate software update file on the host, and click OK.
10. Install PAN-OS software updates.

    To avoid downtime when updating the software on high availability (HA) firewalls, update one HA peer at a time.

    For active/active firewalls, it doesn’t matter which peer you update first.

    For active/passive firewalls, you must update the passive peer first, suspend the active peer (fail over), update the active peer, and then return the active peer to a functional state (fail back).

    (SD-WAN only) To preserve an accurate status for your SD-WAN links, you must upgrade your hub firewalls to PAN-OS 10.2 before you upgrade your branch firewalls. Upgrading branch firewalls before hub firewalls may result in incorrect monitoring data (PanoramaSD-WANMonitoring) and for SD-WAN links to erroneously display as down.

    1. Perform the steps that apply to your firewall configuration to install the PAN-OS software update you just uploaded.

       • Non-HA firewalls—Click Install in the Action column, select all the firewalls you are upgrading, select Reboot device after install, and click OK.
       • Active/active HA firewalls:
         1. Confirm that the preemption setting is disabled on the first peer that you intend to upgrade (DeviceHigh Availability > Election Settings). If enabled, then edit Election Settings and disable (clear) the Preemptive setting and Commit your change. You need only disable this setting on one firewall in each HA pair but ensure that the commit is successful before you proceed.
         2. Click Install, disable (clear) Group HA Peers, select either HA peer, select Reboot device after install, and click OK. Wait for the firewall to finish rebooting before you proceed.
         3. Click Install, disable (clear) Group HA Peers, select the HA peer that you didn’t update in the previous step, Reboot device after install, and click OK.

       • Active/passive HA firewalls—In this example, the active firewall is named fw1 and the passive firewall is named fw2:
         1. Confirm that the preemption setting is disabled on the first peer that you intend to upgrade (DeviceHigh Availability > Election Settings). If enabled, then edit Election Settings and disable (clear) the Preemptive setting and Commit your change. You need only disable this setting on one firewall in each HA pair but ensure that the commit is successful before you proceed.
         2. Click Install in the Action column for the appropriate update, disable (clear) Group HA Peers, select fw2, Reboot device after install, and click OK. Wait for fw2 to finish rebooting before you proceed.
         3. After fw2 finishes rebooting, verify on fw1 (Dashboard > High Availability) that fw2 is still the passive peer (the Local firewall state is active and the Peer—fw2—is passive).
         4. Access fw1 and Suspend local device (DeviceHigh AvailabilityOperational Commands).
         5. Access fw2 (Dashboard > High Availability) and verify that the Local firewall state is active and the Peer is suspended.
         6. Access Panorama, select PanoramaDevice DeploymentSoftware, click Install in the Action column for the appropriate release, disable (clear) Group HA Peers, select fw1, Reboot device after install, and click OK. Wait for fw1 to finish rebooting before you proceed.
         7. Access fw1 (DeviceHigh AvailabilityOperational Commands), click Make local device functional, and then wait two minutes before you proceed.
         8. On fw1 (Dashboard> High Availability), verify that the Local firewall state is passive and the Peer (fw2) is active.
    2. After you complete the above steps for a PAN-OS release update, repeat Step 8 and Step 9 to upload the next PAN-OS release in your upgrade path as needed until all firewalls are running the target PAN-OS 10.2 release.
11. (FIPS-CC mode only) Upgrade Panorama and Managed Devices in FIPS-CC Mode.

    Upgrading a managed firewall in FIPS-CC mode requires you to reset the secure connection status if you added the Dedicated Log Collector to Panorama management while the managed firewall was running a PAN-OS 10.2 release.

    You do not need to re-onboard the managed firewall added to Panorama management while the managed firewall was running a PAN-OS 10.0 or earlier release.
12. Verify the software and content versions that are installed on each managed firewall.

    1. Select PanoramaManaged Devices.
    2. Locate the firewall and review the values in the Software Version, Apps and Threat, Antivirus, URL Filtering, and GlobalProtect Client columns.
13. 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.
14. On the Panorama web interface, push the entire Panorama managed configuration to your managed firewalls firewalls.

    This step is required to enable selective commit and push of device group and template stack configuration changes from Panorama to your managed firewalls.

    This is required to successfully push configuration changes to multi-vsys firewalls managed by Panorama after successful upgrade to PAN-OS 10.2. For more information, see the change to default behavior for shared configuration objects for multi-vsys firewalls managed by Panorama.

    1. Select CommitPush to Devices.
    2. Push.
15. Regenerate or re-import all certificates to adhere to OpenSSL Security Level 2.

    On upgrade to PAN-OS 10.2, it is required that all certificates meet the following minimum requirements:

    • RSA 2048 bits or greater, or ECDSA 256 bits or greater
    • Digest of SHA256 or greater

    See the PAN-OS Administrator's Guide or Panorama Administrator's Guide for more information on regenerating or re-importing your certificates.
