Hi,
I'm planning a upgrade on stacked switches, two C9500 high performance.
It is running in bundle mode at the moment, and I want to set it up in install mode instead.
I'm not very used to install mode. But I fear that if it would fail, would it work the same way as I could set up a second boot command telling it to revert back into bundle mode with old firmware?
What is your experience with upgrading, will the stack go down, or will each switch reboot one at a time?
It's not very well documented the behavior. Would appreciate if someone more experienced could explain in more detail.
