I need to upgrade the memory on our PIX 515 active-standby failover pair in order to upgrade to 7.2.1...I am intending on:
Powering off standby
Power up standby, let it resync.
Fail primary so standby becomes active
Power down primary
Upgrade RAM in primary
Power up primary, force failover back (no preempt).
Does this sound sensible?
Also, I'm upgrading from 6.3 to 7.2.1 - does anyone know of a tool that you can run your config through to pick up potential issues? I've been through the guide and I think everything's going to be OK, but I've heard that you can also do this.
