I currently have two C9500-48 switches.
One of them is in production (with working configuration)
And the other switch is in stock (without configuration).
Now I want to form a stackwise between both switches.
then I will configure both switches to form stackwise, connect them together and reboot to form stackwise.
What happens with my configuration of my productive switch, does it remain or will it be deleted???
Before restarting, how can I define that my switch that is currently in production is the primary one and the switch that I had in stock is the secondary one???
