Upgrade Log Collectors When Panorama Is Internet-Connected

Upgrade Log Collector software to PAN-OS® 11.1 and install content updates using Panorama™ when Panorama is connected to the internet.
For a list of software or content updates you can install on Log Collectors, see Supported Updates.
If you are upgrading from PAN-OS 8.1, PAN-OS 9.0 introduced a new log data format for local and Dedicated Log Collectors. On your upgrade path to PAN-OS 10.1, existing log data is automatically migrated to the new log data format when you upgrade from PAN-OS 8.1 to PAN-OS 9.0.
You must upgrade all Log Collectors in a collector group at the same time to avoid losing log data. No log forwarding or log collection occurs if the Log Collectors in a collector group are not all running the same PAN-OS version. Additionally, the log data for the Log Collectors in the collector group is not visible in the
ACC
or
Monitor
tabs until all Log Collectors are running the same PAN-OS version. For example, if you have three Log Collectors in a collector group and you upgrade two of the Log Collectors, then no logs are forwarded to any Log Collectors in the collector group.
Palo Alto Networks recommends that you upgrade Log Collectors during a maintenance window. Due to log format migration, the entire upgrade procedure takes an additional number of hours depending on the amount of log data on the local and Dedicated Log Collectors.
  1. Before you upgrade Log Collectors, ensure that you are running the appropriate Panorama™ software release on the Panorama management server.
    Palo Alto Networks® highly recommends that Panorama and Log Collectors run the same software release version and that Panorama, Log Collectors, and all managed firewalls run the same content release version. For important software and content compatibility details, see Panorama, Log Collector, Firewall, and WildFire Version Compatibility.
    Panorama must be running the same (or later) software release as Log Collectors but must have the same or later content release version:
    • Software release version
      —If your Panorama management server is not already running the same or a later software release than the release to which you intend to update Log Collectors, then you must install the same or a later Panorama release on Panorama (see Install Content Updates and Software Upgrades for Panorama) before you update any Log Collectors.
    • Content release version
      —For content release versions, you should ensure that all Log Collectors are running the latest content release version or, at minimum, running a later version than is running on Panorama; if not, then first Upgrade the Firewall to PAN-OS 11.1 from Panorama and then update Log Collectors before you update the content release version on the Panorama management server.
    To check software and content versions:
    • Panorama management server
      —To determine which software and content versions are running on the Panorama management server, log in to the Panorama web interface and go to General Information settings (
      Dashboard
      ).
    • Log Collectors
      —To determine which software and content versions are running on Log Collectors, log in to the CLI of each Log Collector and run the
      show system info
      command.
  2. Enable the following TCP ports on your network.
    These TCP ports must be enabled on your network to allow inter-Log Collector communication.
    • TCP/9300
    • TCP/9301
    • TCP/9302
  3. You cannot skip installation of any feature release versions in the path from the currently running PAN-OS version to PAN-OS 11.1.0.
    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.
  4. Install the latest content updates.
    Refer to the Release Notes for the minimum content release versions required for a Panorama software release.
    1. Select
      Panorama
      Device Deployment
      Dynamic 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 appropriate content updates. After a successful download, the link in the Action column changes from
      Download
      to
      Install
      .
    3. Install
      the content update (Applications and Threats update) before any others.
      If your subscription includes both Applications and Threats content, install the
      Apps
      content first. This automatically installs both Application and Threats content.
      Regardless whether your subscription includes both Applications and Threats content, Panorama installs and needs only the Applications content. For details, see Panorama, Log Collector, Firewall, and WildFire Version Compatibility.
    4. Repeat the substeps above for any other updates (Antivirus, WildFire, or URL Filtering) as needed, one at a time, and in any sequence.
  5. Upgrade the Log Collector to the PAN-OS releases along your upgrade path to PAN-OS 11.1.
    If upgrading more than one Log Collector, streamline the process by determining the upgrade paths for all Log Collectors you intend to upgrade before you start downloading images.
    1. PAN-OS 11.1 introduces a new log format. On upgrade from PAN-OS 11.1 to PAN-OS 10.1, you can choose to migrate logs generated in PAN-OS 8.1 or earlier release. Otherwise, these logs are automatically deleted on successful upgrade to PAN-OS 10.1. During migration, log data is not visible in the ACC or Monitor tabs. While the migration takes place, log data continues forwarding to the appropriate Log Collector but you may experience some impact to performance.
  6. Upgrade the Log Collector to PAN-OS 11.1.
    1. On Panorama,
      Check Now
      (
      Panorama
      Device Deployment
      Software
      ) for the latest updates. If an update is available, the Action column displays a
      Download
      link.
    2. Download
      the model-specific file for the release version of the PAN-OS 11.1 release. For example, to upgrade an M-Series appliance to Panorama 11.1.0, download the
      Panorama_m-11.1.0
      image.
      After a successful download, the Action column changes from
      Download
      to
      Install
      for that image.
    3. Install
      PAN-OS 11.1 and select the appropriate Log Collectors.
    4. Select one of the following depending on your needs:
      • Upload only to device (do not install)
        .
      • Reboot device after install
        .
    5. Click
      OK
      to start the upload or installation.
  7. Verify the software and content update versions that are installed on the Log Collector.
    Enter the
    show system info
    operational command. The output will resemble the following:
    sw-version: 11.1.0 app-version: 8750-8261 app-release-date: 2023/08/31 03:57:2
  8. Upgrading a Dedicated Log Collector in FIPS-CC mode requires you to reset the secure connection status if you added the Dedicated Log Collector to Panorama management while the Dedicated Log Collector was running a PAN-OS 11.1 release.
    You do not need to re-onboard the Dedicated Log Collector added to Panorama management while the Dedicated Log Collector was running a PAN-OS 10.0 or earlier release.
  9. (
    PAN-OS 10.2 and later releases
    ) Regenerate or re-import all certificates to adhere to OpenSSL Security Level 2.
    This step is required if you upgrade from PAN-OS 10.1 or earlier release to PAN-OS 11.0. Skip this step if you upgrade from PAN-OS 10.2 and have already regenerated or re-imported your certificates.
    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.
  10. (
    Recommended for Panorama virtual appliance
    ) Increase the memory of the Panorama virtual appliance to 64GB.
    After you successfully upgrade the Panorama virtual appliance in Log Collector mode to PAN-OS 11.1, Palo Alto Networks recommends increasing the memory of the Panorama virtual appliance to 64GB to meet the increased system requirements to avoid any logging, management, and operational performance issues related to an under-provisioned Panorama virtual appliance.
