I'm getting ready to upgrade two CSS's in box-to-box redundancy mode.
The upgrade is simple enough, but what are the best practices for two boxes in box-to-box?
I suppose I can copy the software up to the master box. Then force the standby box to be master and copy up the software to the standby.
Perform the upgrade/reboot on the standby. Then once the standby is again operational, do the master.
Seems cumbersome. Any suggestions?
