Queue-sharing group migration

You can combine queue managers from different releases in a queue-sharing group. Limit the time you manage a mixed group to only as long as it takes to migrate all the queue managers to the same command level. You cannot combine a queue manager at Version 8.0 or later in the same queue-sharing group as queue managers earlier than Version 7.0.1. You must update all queue managers in a queue-sharing group with a coexistence PTF, before migrating any of them. All queue managers in the queue-sharing group must be at the same version before any queue manager can be migrated to Version 8.0.

When you migrate queue managers in a queue-sharing group, aim to migrate all the queue managers to the new version as soon as you can. Queue-sharing groups can contain queue managers with a restricted mixture of versions. A mixture of queue managers in a queue-sharing group is supported so that you can migrate and test the upgrade of each queue manager. Migrate each queue manager, one at a time, leaving the queue-sharing group running. Mixed groups are harder to administer, than if all the queue managers are at the same version.
