Palo Alto Networks | PAN-229865

The earliest recollection of this bug is traced back to PAN-OS 10.2.6 - May 16, 2024. This bug is fixed in PAN-OS versions 10.2.6. ( PA-220 firewalls only ) Fixed an issue where upgrading to PAN-OS 10.2.5 failed if the firewall was on a PAN-OS 10.1 release. Upgrading a PA-220 firewall running a PAN-OS 10.1 release fails when the target PAN-OS upgrade version is PAN-OS 10.2.5. Workaround: On your upgrade path to PAN-OS 10.2.5, first upgrade to PAN-OS 10.2.4 and then upgrade to PAN-OS 10.2.5.
