Hello! I have two questions: - Is there any downtime during the upgrade? For example, in our case we have deployed 3 gateway locations, if just one location is being upgraded at a time we won't have any downtime right? Because we have other 2 locations operating. - When choosing the upgrade preference, what is the best practice? Choosing the main gateway location we use or upgrading first a gateway location we don't normally use? Thanks & Regards.
