PA850 Firewall OS Upgradation

G.Parab106282 — Tue, 11 Mar 2025 02:24:28 GMT

Hi,

We have two PA 850 firewalls in HA mode. Last week, we upgraded the firmware from 10.2.10-h7 to 11.1.4-h7. However, we now want to upgrade to the latest version, 11.1.6-h3.

Could you please confirm whether this version is stable and free of major bugs? Can we proceed with upgrading to 11.1.6-h3?
