The way you downgrade a firewall from PAN-OS 10.2 depends
on whether you are downgrading to a previous feature release (where
the first or second digit in the PAN-OS version changes, for example,
from 9.1.2 to 9.0.8 or from 9.0.3 to 8.1.14) or downgrading to a
maintenance release version within the same feature release (where
the third digit in the release version changes, for example, from
8.1.2 to 8.1.0). When you downgrade from one feature release to
an earlier feature release, you can migrate the configuration from
the later release to accommodate new features. To migrate the PAN-OS
10.2 configuration to an earlier PAN-OS release, first restore the
configuration for the feature release to which you are downgrading. You
do not need to restore the configuration when you downgrade from
one maintenance release to another within the same feature release.
