The way you downgrade a firewall from PAN-OS 8.0 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 8.0.2 to 7.1.7 or from 7.1.6 to 7.0.9) or downgrading to a maintenance release version within the same feature release (where the third digit in the release version changes, for example, from 8.0.2 to 8.0.0). 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 8.0 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.
