Hello and sorry for my english,
I have two switches C3850 connect by stackwise (fiber). i 'd like tu upgrade switches to new IOS.
How i can do it ?
i 'd like to upgrade one of the two switch, reboot, wait for reboot, upgrade the second switch, reboot because i don't want interruption of the production. it is possible ?
thanks a lot

Hi
If they are in stack means they are like one device. If you want to upgrade individually you need to break the stack first. But, most probably the switch reload anyway.
Long story short, it is not possible upgrade those devices without cause network interruption at some point.
Unless you have another switch or switch stack in paralel with the same function on the network
