The following table lists the new features that have upgrade or downgrade impacts. Make sure you understand all potential changes before you upgrade to or downgrade from a PAN-OS 8.0 release. For additional information about PAN-OS 8.0 releases, refer to the PAN-OS 8.0 Release Notes.
For M-100 appliances running in Panorama mode, Palo Alto Networks recommends upgrading the memory to 32GB to avoid the risk of running out of memory for management and log collection tasks. See M-100 Memory Upgrade Guide for more information.
After upgrading a PA-7000 Series firewall to 8.0, Panorama no longer considers it as a Log Collector. This means you will no longer be able to view your logs and reports from Panorama until you enable PA-7000 Series Firewall Log Forwarding to Panorama. Before upgrading, make sure you have a log collection infrastructure that will handle the logging rate and quantity of PA-7000 Series logs.
- To deploy VM-Series firewalls on AWS in a high availability configuration, you must upgrade to PAN-OS 8.0.1.
- Upgrading a PA-200 or PA-500 firewall to PAN-OS 8.0 can take 30-60 minutes to complete. Ensure uninterrupted power to your firewall throughout the upgrade process.
To ensure optimal performance for all new features, download and install the latest Applications and Threats, Antivirus, and WildFire content updates (the minimum content versions required for PAN-OS 8.0 are listed in the PAN-OS 8.0 Release Notes). As a best practice, enable the firewall to download and install new content updates as they become available.
Hardware Security Modules
PAN-OS 8.0.2 and later releases) To downgrade to a release earlier than PAN-OS 8.0.2, you must ensure that the master key is stored locally on Panorama or on the firewall, not on a hardware security module (HSM).
Support for Third-Party SFP Transceivers
A small percentage of writable third-party SFP transceivers (not purchased from Palo Alto Networks) can stop working or experience other issues after you upgrade the firewall to which they are connected to a PAN-OS 8.0 release. Because it is typically impossible to know if a third-party SFP is writable, Palo Alto Networks® recommends that, if your firewall uses third-party SFPs, you do not upgrade to a PAN-OS 8.0 release until you are able to upgrade to a maintenance release that addresses this issue. Additionally, when you are ready to upgrade, make sure that you do not reboot the firewall after you download and install the PAN-OS 8.0 base image until after you download and install a maintenance release that contains the fix for this issue.
This will be the case again if you upgrade to PAN-OS 8.1 even after you address this issue in PAN-OS 8.0.
For more information about this known issue and maintenance releases related to this issue, refer to the PAN-OS 8.0 release notes.
Log Query Acceleration on Panorama
When you upgrade Panorama and the Log Collectors to PAN-OS 8.0, logs generated from earlier PAN-OS versions will be unavailable when viewing charts on the ACC and when generating reports until you migrate the logs to the new format. Refer to Migrate Existing Logs to the New Log Format introduced in PAN-OS 8.0.
When you downgrade Panorama and the Log Collectors from Panorama 8.0, you will need to migrate logs back to the pre-8.0 format. This procedure will take approximately 24 hours for each 2TB of data. You cannot pause or stop the migration, so you will need to schedule a maintenance window to accommodate. To downgrade, refer to Downgrade from Panorama 8.0.
With the log query and reporting engine enhancements that improve the speed in generating reports and executing queries, note that the logging rates on the M-Series appliances are lower than in previous Panorama releases. For maximum logging rates in PAN-OS 8.0, see Panorama Models.
PAN-OS 8.0 introduces two new log types (Palo Alto Networks Platform Logs and 3rd Party External Logs). On upgrade, 4% of the total disk space is allocated for the new log databases. As a result, if Panorama or the Dedicated Log Collector do not have 4% of total disk space, the oldest logs are purged to make space available.
IKE Peer and IPSec Tunnel Capacity Increases
The firewall prevents a downgrade if the number of IKE gateways or IPSec tunnels you are using in PAN-OS 8.0 exceeds the product limit for the release to which you are downgrading. To successfully download in this case, first delete the oversubscribed IKE peers or IPSec tunnels to the number supported in the downgraded release and then downgrade. Alternatively, restore a compatible configuration and downgrade.
VM-Series Firewall Performance Enhancements
Downgrading from PAN-OS 8.0 to an older release returns VM-Series models to their pre-PAN-OS 8.0 capacities and performance levels. Downgrading a VM-50, VM-500, or VM-700 firewall is not supported.
Authentication for External Dynamic Lists
Telemetry and Threat Intelligence Sharing
External Dynamic List Enhancements
After you upgrade, you have the option to customize the service route that the firewall uses to retrieve an external dynamic list from the web server that hosts the list.
Palo Alto Networks Malicious IP Address Feeds
Globally Unique Threat IDs
Data Filtering Support for Data Loss Prevention (DLP) Solutions
Data pattern objects defined with both regular expression patterns and social security number and credit card patterns are separated into two separate data pattern objects following the upgrade to PAN-OS 8.0: one data pattern object contains the regular expression patterns, the other contains the social security and credit card number patterns. The separate data pattern objects continue to remain attached to data filtering profiles they were configured with before the PAN-OS 8.0 upgrade. To learn more, take a First Look at New and Updated Data Filtering Options.
Tunnel-Mode on GlobalProtect Gateways
If you enable tunneling on a GlobalProtect internal gateway and then downgrade to an older release of PAN-OS, the gateway is removed and you must reconfigure the gateway after you downgrade.
If you saved a PAN-OS 7.1 configuration that includes tunnel-mode gateways and you want to restore the configuration, downgrade the firewall from PAN-OS 8.0 to PAN-OS 7.1 first, then select and commit the saved PAN-OS 7.1 configuration.
GlobalProtect External Gateways
For GlobalProtect agent configurations where you configured an external gateway with a
Manual onlypriority (connections are not established automatically) and disabled
Manualconnections (users cannot manually switch to the gateway), GlobalProtect will add a
Manual onlypriority rule and activate (enable)
Manualconnections when you upgrade. This allows users to manually switch to the gateway, which is required to support External Gateway Priority by Source Region.
GlobalProtect Portal Authentication
PAN-OS 8.0.5 and later releases) After you upgrade to PAN-OS 8.0.5 or a later release, users who have endpoints with valid authentication override cookies but who were removed from the Allow List of authentication profiles cannot access GlobalProtect portals or gateways (internal or external). This prevents users with valid cookies but disabled accounts from accessing the portals and gateways.
PAN-OS 8.0.5 and later releases) After you downgrade to PAN-OS 8.0.4 or an earlier release, user endpoints with valid authentication override cookies can access a GlobalProtect portal or gateway (internal or external) even if the corresponding user accounts were disabled and removed from the Allow List of authentication profiles. You must reconfigure policies (using dynamic block lists or source address/user lists) to prevent portal and gateway access in such cases.
Authentication Policy and Multi-Factor Authentication
GlobalProtect Included Access Route Capacity Enhancement
When you upgrade Panorama to version 8.0.2 or a later release, you cannot push templates containing 200 or more GlobalProtect include access routes to firewalls running PAN-OS 8.0.1 or earlier releases. To push more than 200 access routes, you must upgrade the firewalls to PAN-OS 8.0.2 or a later release. Otherwise, you must remove access routes from the template until there are 200 or fewer access routes.
When you downgrade a firewall to PAN-OS 8.0.1 or an earlier release, a GlobalProtect configuration with more than 200 include access routes will cause a commit fail. To resolve the issue, you must remove access routes until the configuration contains 200 or fewer access routes.
Selective Log Forwarding Based on Log Attributes
Upon downgrading, the only log attribute that the firewall will preserve as a filter in Log Forwarding profiles and
entries will be the log severity level.
Log Forwarding from PA-7000 Series Firewalls to Panorama
After upgrading a PA-7000 Series firewall, Panorama no longer considers the firewall as a Log Collector and you will no longer be able to view logs and reports from Panorama until you enable log forwarding.
Before upgrading PA-7000 Series firewalls to PAN-OS 8.0, make sure your Log Collectors have enough capacity to support the log collection rates and volume of logs your PA-7000 Series firewalls will forward to Panorama. See the table in Panorama Models to determine your log collection requirements.
After you enable log forwarding to Panorama, the firewall forwards only new logs. To view log information on Panorama and generate reports from logs generated prior to enabling log collection, you must migrate existing logs to Panorama using a CLI command. See PA-7000 Series Firewall Log Forwarding to Panorama for more details.
Upgrading a PA-7000 Series Firewall with a first generation switch management card (PA-7050-SMC or PA-7080-SMC)
Before upgrading the firewall, run the following CLI command to check the flash drive’s status:
debug system disk-smart-info disk-1.
If the value for attribute ID #232,
Available_Reservd_Space 0x0000, is greater than 20, then proceed with the upgrade. If the value is less than 20, then contact support for assistance.
Before downgrading the firewall, run the following CLI command to check the flash drive’s status:
debug system disk-smart-info disk-1.
If the value for attribute ID #232,
Available_Reservd_Space 0x0000, is greater than 20, then proceed with the downgrade. If the value is less than 20, then contact support for assistance.
Logging Enhancements on the Panorama Virtual Appliance
After upgrading, the Panorama virtual appliance remains in Legacy mode by default and can still support NFS log storage. However, after you switch to Panorama mode, the virtual appliance can no longer support NFS storage; you must then migrate the logs on the NFS to the Log Collectors.
Before downgrading, you must switch the Panorama virtual appliance from Panorama mode to Legacy mode. To store logs after switching the mode, you must use the old virtual disk or NFS storage that Panorama used for logging in Legacy mode.
Group-Based Reporting in Panorama
After upgrading Panorama, you must
Enable reporting and filtering on groupsin the Panorama settings (
) if you want to filter logs and generate reports based on user groups; the option is disabled by default. If you want to disable this feature for specific device groups, you must clear the
Store users and groups from Master Deviceoption in those device groups (
); the option is enabled by default.
User-ID Syslog Monitoring Enhancements
After upgrading, you must set the
loginfor every existing Syslog Parse profile assigned to syslog senders in the Server Monitoring list (
Windows-based User-ID Agent
After you uninstall the PAN-OS 8.0 Windows-based User-ID agent, perform the workaround described in Downgrade a Windows Agent from PAN-OS 8.0 before you install an earlier agent release.
A PAN-OS 8.0 release of the Windows-based User-ID agent works with firewalls running a release earlier than PAN-OS 8.0.
NSX VM-Series Configuration Through Panorama
Packet Buffer Protection and Zone Protection Profile
If you enable Packet Buffer Protection or you configure a Zone Protection profile with
strictevasion protection, and downgrade to a PAN-OS 7.1 release, the downgrade fails with auto-commit errors.
If you saved a PAN-OS 7.1 configuration before upgrading, select the PAN-OS 7.1 configuration when downgrading. This removes the Packet Buffer Protection configuration and allows downgrade to complete successfully.
ECMP Enhancement to IP Hash (
PAN-OS 8.0.3 and later releases)
If the ECMP IP Hash setting is configured to
Use Source Address Onlyand you want to downgrade from PAN-OS 8.0.3 (or a later release) to PAN-OS 8.0.2 or an earlier PAN-OS 8.0 release, first save your PAN-OS 8.0.3 (or later) running configuration. Then perform the downgrade and, after the downgrade is complete, reload your saved configuration and
After you downgrade from a PAN-OS 8.0 release to PAN-OS 7.1.15 or an earlier release, you must reset the QoS
Egress Maxto 16,000 Mbps or less to avoid commit failures (
BGP Minimum Route Advertisement Interval
If you upgrade from a PAN-OS version earlier than PAN-OS 8.0.11 (such as PAN-OS 7.1, PAN-OS 8.0, or PAN-OS 8.0.1) to PAN-OS 8.0.11, you can use the CLI operational command
setsystem setting bgp-mrai-timer valueto configure a BGP minimum route advertisement interval for all BGP peer groups (range is 1 to 600 seconds; default is 30 seconds).
If you downgrade from PAN-OS 8.0.11 (or a later PAN-OS 8.0 release) to a release earlier than PAN-OS 8.0.11, the BGP minimum route advertisement interval that you configured with the CLI operational command
set system setting bgp-mrai-timer valuereverts to the hard-coded value of 30 seconds.
