Hey guys, it looks like we are having an issue with a stack that has 5 nodes. At some point or another a node will fail so it came to be that all nodes will be replaced in this stack. My question is that since I have a limited time frame of 2 hours, would it be best to do 1 node at a time starting from 5 and work my way up to 1 (Master) or do I set up the new stack and copy config files? More than likely the new switch's will have newer image than what we currently have. I've swapped out nodes before but have never been faced with a situation like this.
