Create a migration plan for a queue manager cluster
Before carrying out the migration of a queue manager cluster, plan what we are going to do. Identify the roles that different queue managers play in the cluster, and decide in what order to migrate the queue managers.
Procedure
- What queue manager and application migration issues must be dealt with between the old and new versions?
- What system architecture and change control procedures must you consider?
- Consider migration questions specific to clusters, such as migrating full repositories first, and migrating overlapping clusters.
- Are any of the queue managers in a queue sharing group, or part of a high-availability solution?
- Is the cluster a publish/subscribe cluster? Which queue manager is a cluster topic host?
- Decide whether to carry out a staged migration, or migrate all queue managers at the same time.
- Do you have a test system to migrate, and a production system?
- Document and test the plan before migrating production queue managers.
