v11 upgrade without downtime for active/standby pair?

Although if all your profiles have loose-initiation (Or there's no active connections) and there's no passive style persistence, then you should be able to get away with it... But it's a big if because anything relying on source IP for persistence for example won't have the persistence state.

 

 

Although you could gets round that by ensuring that before the upgrade only 1 pool member was enabled... Then there's no trouble for re-selecting. That and loose-init might get you through it. Might be more than you're willing to change though.
