Migrating a queue manager cluster

This section gives information about migrating queue manager clusters to WebSphere® MQ Version 6.0.

Migrate the repository queue managers (that is, those queue managers holding a full repository) first, before migrating the other queue managers.

WebSphere MQ Version 6.0 introduces new workload balancing attributes on queues, queue managers, and channels. See Chapter 12 of WebSphere MQ Queue Manager Clusters for full details of these attributes. If these parameters are left at their default values, the queue managers will behave as they did before migration.

Use of the new workload balancing parameters in a cluster containing a mixture of Version 5.3 and Version 6.0 queue managers will give unpredictable results.
