We’ll be upgrading two FortiGates configured in Active-Passive HA. Is it possible to have one FortiGate running on the upgraded version for testing while keeping the other on the previous version? Or is it necessary to upgrade both FortiGates to the same FortiOS version for HA to function properly? This is a production environment, so I'd like to know if I can upgrade one FortiGate first to test the stability of the upgrade and HA with the FortiGate running on the original version.

Not sure about what's "460" but there is no FortiOS 10.x.x. The current latest is 7.6.x.
Also not sure what you mean by "suspended". Did you mean "halt" it by "exe shutdown"? Or, you meant "isolating it" by shutting down all interfaces into that unit on the opposite side (like a switch, and the other side of HA cable)?

Hi @aj-fernandez ,
First of all, you can't do it that way.
Secondly, I would recommend you run a PoC test in your lab, not on your production FGT HA cluster.
