ASA 5520 Active/Standy - Upgrading IOS

Hi,

I'm looking to upgrade from 8.0(2) to 8.0(3). We currently have a cable failover connection between the active/standby. I'm trying to find documentation on the procedure to upgrade them without affecting anyone currently connected. Do you upgrade the standby, reload it, then do the "no failover standby" to flip it from secondary to primary? I've seen it done once very fast, and I was told it's documented on Cisco's site, but I have not been able to find it. I'm positive I'm missing some steps. Anyway, if someone could point me to the documentation or send me the procedures, that would be terrific. Thanks in advance!

This may help, refer to table 41-1 zero-downtime upgrade support / upgrading an active/Standby failover configuration..
