I want to upgrade PA-3220 (Active - Passive) from 8.1.14 to 9.1.10
Is this upgrade method correct or not?
1.Download and install PanOS 9.0.0 (no reboot) Should I upgrade PanOS to 8.1.19 (Preferred release) or not?
2.Download and install PanOS 9.0.13 and reboot
3.Download and install PanOS 9.1.0 (no reboot)
4.Download and install PanOS 9.1.10 and reboot
I'm not sure the step to rollback 9.1.10 to 8.1.14. Can you help recommend steps to downgrade?

Hi @jirasith
(Firewall A = currently active firewall, firewall B = currently passive firewall)
To make sure that you can downgrade in case of any problems export the configuration at all of the following steps on both firewalls:

@vsys_remo Thank you for the advice. If I have to downgrade the firmware version from 9.1.10 to 8.1.19. Can I revert the upgrade path such as
1.Download and install 9.0.13
2.Download and install 9.0.0 and reboot
3.Download and install 8.1.19 and reboot
or Can I directly download and install 8.1.19?

@jirasith In case of a downgrade you first go to 9.0.13 and then to 8.1.19. You don't need the step to install and reboot for the version 9.0.0.
