Hi all. Quick question.
Need to upgrade firmware on High Availability (Hardware Failover) Pair.
Reading the instruction on the below link, it looks that i can run the update with no interuption on the traffic.
Can you please confirm that?

@katsogiannis depending on your WAN Interfaces you might experience a drop of a few packets. Stateful-HA needs to be licensed to have a smooth transition.
If you're running something like PPPoE on your WAN interface it might take a while to reconnect, these connections are not synced..
