I need to upgrade our current production 2.7.1 RabbitMQ cluster to it's new
In our production cluster, we have 2 disc node and erlang R15B installed.
According to the RabbitMQ cluster guilde:
"All nodes in a cluster must be running the same versions of Erlang and
RabbitMQ, although they may have different plugins installed. Therefore it
is necessary to stop all nodes in the cluster, then start all nodes when
performing an upgrade."
In our case we cannot shutdown our existing cluster, because it is heavily
used to send messages across regions.
Could someone please let me know how to upgrade 2.7.1 cluster without
shutdown the entire cluster.
