I'm not exactly sure if I'm thinking about this right, could you please advise?
I have two PIX's running in statefull active/standby failover. I want to upgrade those from 7.0(2) to 7.0(6).
I figured out that what I need to do is:
- go to the standby PIX and do a copy of image into the pix and reload the pix.
- make the standby node (the one I just upgraded) active by doing a "failover active" on the failover device.
- do the same thing on the other device which is now in the standby mode.
and that should not impact my availability, since I will always be upgrading the standby node. could you advise if this is right?
maybe some docs on this?
