Downgrade a Firewall to a Previous Feature Release
Downgrade to a previous feature release.
Use the following workflow to restore the
configuration that was running before you upgraded to a different
feature release. Any changes made since the upgrade are lost. Therefore,
it is important to back up your current configuration so you can
restore those changes when you return to the newer feature release.
Use
the following procedure to downgrade to a previous feature release.
Save a backup of the current configuration file.
Although the firewall automatically
creates a backup of the configuration, it is a best practice to
create a backup before you upgrade and store it externally.
Export named configuration snapshot
().
Select the XML file that contains your running configuration (for
example,
running-config.xml
) and click
OK
to
export the configuration file.
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 downgrade.
Install the previous feature release image.
Autosave versions are created when you upgrade to
a new release.
Check Now
()
for available images.
Locate the image to which you want to downgrade. If
the image is not already downloaded, then
Download
it.
After the download completes,
Install
the
image.
Select a Config File for Downgrading
,
which the firewall will load after you reboot the device. In most
cases, you should select the configuration that was saved automatically when
you upgraded from the release to which you are now downgrading.
For example, if you are running PAN-OS 9.1 and are downgrading to
PAN-OS 9.0.4, select
autosave-9.0.4
.
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, go to Device Operations ()
and
Reboot Device
.
