We're preparing to upgrade our cluster from 1.0.0 to 1.3.0. We're using external zookeeper.
We're wondering if we can simply expand the cluster with 1.3.0 machines and then turn off the other ones to keep processes running. Are there issues with attempting that? Is there an upgrade guide someone for clusters on Wiki? We have kafka consumers and other maintenance processes that are running in production so we'd like to make the change without messing with the state of those consumers if possible.
