Software upgrade to a failover pair of Pix 525s - any caveats?
I have a failover pair of PIX 525's (in production) and want to upgrade the firmware on both of them (probably from 6.3 to 6.35 and maybe later on to 7.x). With the failover pair - should I power one down and do the upgrade on the other first, then power up the second and do that one ? Is there a recommended sequence here with upgrading them ? I thought I heard somewhere you need to be careful how you do these upgrades with a failover pair
