Proper Order to Upgrade Primary/Secondary Failover ASA

[Michael All]

Greeting everyone!

I'm looking to see if anyone has a link or information regarding the proper procedure for upgrading two ASA5520s in a Primary/Secondary Failover configuration? This will be an upgrade to the ASA Software and the ASDM Software.

Thanks for your help in advance!
