I am wanting to use the basic Cisco documents about upgrading my current stack to 16.03.05 from 03.06.05E. Are there any special considerations? I am only a CCENT with limited experience. I don't want to ruin my stack.
I am backing up my configs and VTP database.
I believe the switch can be added while the stack is on. Is this true? What order would I unplug the stack cables?
Since it is a stack, will each switch take turns upgrading and avoid any downtime?
