If firewall with HA configured can we upgrade firmware from centralized manager also if we do both device will reboot same time ?

Hi..., I have two Fortinet 100F in an A-P cluster, with firmware v6.4.5 and I want to upgrade to v7.2.4.
From what I can see in the GUI, the upgrade roadmap involves 4 intermediate versions, to then get to 7.2.4.
My query would be then..., (defining the same Priority for each node and disabling the Override, as you recommend), could I start the upgrade without major considerations and without affecting the user sessions?
And on the other hand, the updates would be progressive, that is to say, first, the whole process of updating to 7.2.4, of a node and then the other ..., or each node would be updated, alternatively, to each intermediate version of the roadmap?
Thank you very much for your time

I see you opened two web-interfaces with different IP-addresses. The second is the web-interface of slave-unit or Forti-manager? Cos in our HA-cluster slave-unit get same IP as master, so I don`t understand what did you check when pinging. Or yours HA mode is Active/Active?..

So, just upgrade the master then the second fortigate will upgrade also ?
