If my understanding is correct (I have done little work with this and have attended no classes) HA for AIX does this. You bring down one system and it failsover to the other. You then apply all upgrades to the OS and HA software and when you are ready to apply it, you bring that system back up and failover to it. redbooks.ibm.com has a lot of their documentation for HA, you might look there for more info.
