Migrating replicated data queue managers

When you need to migrate replicated data queue managers (RDQMs), you must upgrade all nodes in a sequence. Do not try to operate with the nodes at different levels.

About this task

The upgrade sequence for HA RDQM configurations consists of suspending a node, uninstalling IBM MQ and RDQM support, installing the newer version of IBM MQ and RDQM support, then resuming the node. You then move on and repeat this sequence on the next node. Following this sequence ensures that your queue managers continue to run on one of the nodes in the HA group while the migration is in progress.

The upgrade sequence for DR RDQM configurations consists of upgrading the recovery node, running the DR queue managers on the newly upgraded recovery node, upgrading the primary node, switching the DR queue managers back to running on the primary node.

Scripts are provided that you run to uninstall and install IBM MQ and RDQM.

The upgrade location must be the same as the original installation location, and all the nodes must use the same location.
