I am in the process of migrating an HA pair PA-5020 on version 8.1.22 to PA-5220 that shipped with version 10.1.3. From what I researched the 5020 is end of life and can only go up to OS ver to 8.1.*. My thought was to downgrade the new PA-5220 from 10.1.3 to 8.1.22 and restore the configuration. In the process of downgrading the PA5220 to 8.1.22, I got a failed message that said that the firewall cannot go lower than version 10. How can I restore the config if I cannot get the new firewall to the same os level running on the PA5020? Any help will be appreciated.
