Upgrade Firewalls When Panorama Is Internet-Connected

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.
From the Panorama web interface, select
Panorama
Setup
Operations
and click
Export Panorama and devices config bundle
to generate and export the latest configuration backup of Panorama and of each managed appliance.

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.
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 10.0. Make sure to follow the Best Practices for Application and Threat Updates when deploying content updates to Panorama and managed firewalls.
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.

If not already installed,
Download
the latest content release version.
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.

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
setmax-num-images count <number>
CLI command to increase the maximum.
(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.
Select
Device
High Availability
and edit the
Election Settings
.
If enabled, disable (clear) the
Preemptive
setting and click
OK
.

Commit
your change. Make sure the commit is successful before you proceed with the upgrade.
Determine the Upgrade Path to PAN-OS 10.0.
You cannot skip installation of any feature release versions in the path from the currently running PAN-OS version to PAN-OS 10.0.0. 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.
If upgrading more than one firewall, streamline the process by determining upgrade paths for all firewalls before you start downloading images.
Download the target PAN-OS 10.0. release image.
Select
Panorama
Device Deployment
Software
and
Check Now
for the latest release versions.
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.
For example, to upgrade your PA-220 and PA-5250 firewalls to PAN-OS 10.0.0, download the
PanOS_220-10.0.0
,
PanOS_3000-10.0.0
, and
PanOS_5200-10.0.0
images. After you successfully download an image, the Action column changes to
Install
for that image.
Install the PAN-OS 10.0 software update on the firewalls.
You must upgrade your hub firewalls from PAN-OS 10.0.0 to PAN-OS 10.0.1 or later release before you upgrade your branch firewalls. Upgrading branch firewalls before hub firewalls may result in incorrect monitoring data (
Panorama
SD-WAN
Monitoring
) and for SD-WAN links to erroneously display as
down
.
Click
Install
in the Action column that corresponds to the firewall models you want to upgrade. For example, if you want to upgrade your PA-220 firewalls, click
Install
in the row that corresponds to PanOS_220-10.0.0.
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.
(HA firewall upgrades only)
Make sure
Group HA Peers
is not selected.
Select
Reboot device after install
.
To begin the upgrade, click
OK
.
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
Device
Setup
Operations
and
Reboot Device
.
After the firewalls finish rebooting, select
Panorama
Managed Devices
and verify the Software Version is 10.0.0 for the firewalls you upgraded. Also verify that the HA status of any passive firewalls you upgraded is still passive.
(HA firewall upgrades only)
Upgrade the second HA peer in each HA pair.
(Active/passive upgrades only)

(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
Verify the software and content release version running on each managed firewall.
On Panorama, select

Panorama

Managed Devices

.

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.


(HA firewall upgrades only)
If you disabled preemption on one of your HA firewalls before you upgraded, then edit the
Election Settings
(
Device

) and re-enable the
Preemptive
setting for that firewall and then
Commit
the change.
