Hi Brice,

 

 

If you can use serial failover, the standby unit will stay standby. Network failover is not guaranteed to work though. If you're not able to use hardwire failover, here are some rough steps for doing the upgrade with one outage:

 

 

disable the switch ports on the unit B you're upgrading

 

upgrade B

 

re-enable the B switch ports during the maintenance window

 

fail over to B during the maintenance window

 

disable the A switch ports

 

upgrade A
