As far as I know, the standby ASA will not process traffic as long as the active member is alive or has not resign.
I see three possibilities :
1) Test the new IOS in a lab. Best would be to have a spare ASA in the lab. Otherwise you could also remove the standby ASA from live network and make it active in the lab...
2) Perform a failover to the standby, verify everything is working fine then upgrade the second ASA to the same IOS version
3) Break the cluster to have the two ASA Active daisy chain them (some re-IP required). However I do not see any advantage on the proposal 2.
