Subject Upgrading nodes in a cluster
Date Tue, 06 Aug 2013 13:00:45 GMT
If we run 2 or 3 nodes in a cluster with mirrored HA queues, are there any restrictions or
special procedures that must be observed to upgrade the qpid version on individual nodes without
any service interruption? Can different nodes in the cluster run different versions of qpid
or do all the nodes have to be upgraded at the same time (like with RabbitMQ - http://www.rabbitmq.com/clustering.html#upgrading
which then requires a federation of clusters to keep the service available)?
