Migrating a queue manager cluster
Migrate a queue manager cluster by migrating each of the queue managers in the cluster. No changes since Version 6.0 specifically effect the migration of queue manager clusters. But you must consider what the effect is of migrating some queue managers in a cluster, before all the queue managers are migrated.
Before you begin
Check that no cluster-specific migration issues are identified for the migration you are intending to perform. No cluster-specific changes have been made that affect migration between Version 7.0.1 and later versions.
Procedure
Consider the following issues that relate to migrating a queue manager cluster:
- Minimizing application outages.
- Measuring and verifying migration success and planning for backward migration if there are any migration problems.
- Taking advantage of new IBM® MQ features.
- Managing the migration of a cluster in the context of the wider IBM MQ network and the systems architecture of your organization.
Steps
Some techniques for migrating a cluster with minimal planned and unplanned outages are described in the following topics:
