Are you doing a major release update like 7.x to 8.x or are you doing a minor release update from 8.x to 8.y?

Do you need to be able to pass traffic during the upgrade?

If not why not just schedule a maintenace window and do them simultaneously?

my suggestion would be to break the cluster and then upgrade the secondary.  Move it into place and test it for 24 hours.  Then write erase the other, upgrade it, and add it back into the cluster.  This will give you the ability to test the new OS (Always a good idea) as well as a sae failover back to the the old OS in case there are issues.
