Hi Justin, the admin guide[0][1][2] has information that outlines the usual steps and details on what configuration options might need special care. If you have a replicated environment, you can upgrade servers individually or introduce new servers into the cluster and retire the old ones when you switch your live traffic over to the new ones.
