I am getting ready to upgrade my external switch stack and am being asked how long that this upgrade will take the network down. (It will be performed during a maintenance window.) I thought it took about 15-30 minutes but I am not sure of how long that the switch won't function during that time.

Hi,
It depends, if you are upgrading from a very old version, I have seen the reboot time take up to about 20 minutes. If the switch is running a newer version, the reboot time can take up to 15 minutes.

That is good to know as I am moving from one version to another! Nice to have a reference for others that are just going from a sub-version to another.
