As the title would suggest, I'm looking for everyone's experience and info on the behavior of the staged upgrade tool with stacks. I was told a few times by support that the best practice for using the staged upgrade tool is to add all members of the stack to be upgraded to the same window of time. I was also told that after they download the update, there is a "back-off" timer that should prevent them from all rebooting at the same time. I am not finding this to be the case after two stacks I have updated, and in both cases all member rebooted at the same time. I was also told to not try to stagger the updates of switch stack members as this might cause issues with the stack. What is everyone's experience with this scenario? I am updating from 10.26 to 10.45. Any insight is much appreciated!
