During the FTD HA upgrade from FMC, if first standby is failed /corrupted during the upgrade ,will FMC will try to upgrade other devices in the failover pair or will abort the upgrade?.
"By default, FTD automatically reverts to its pre-upgrade state upon upgrade failure ("auto-cancel"). To be able to manually cancel or retry a failed upgrade, disable the auto-cancel option when you initiate the upgrade. In a high availability deployment, auto-cancel applies to each device individually. That is, if the upgrade fails on one device, only that device is reverted."
