Queue sharing group coexistence on z/OS

In general, queue managers running on IBM MQ for z/OS Version 9.2.0 can be part of a queue sharing group with queue managers running on IBM MQ for z/OS Version 9.0.0 or later. This applies to any combination of Continuous Delivery and Long Term Support releases from Version 9.0.0.

Only run queue managers in a mixed-version queue sharing group for the time it takes to migrate all queue managers to the later version.

If any queue manager in the queue sharing group uses data set encryption on its log data sets, every queue manager in the queue sharing group needs to be at Version 9.1.4 or later. If any queue manager in the queue sharing group uses data set encryption on its SMDS, every queue manager in the queue sharing group needs to be at Version 9.1.5 or later.

See Confidentiality for data at rest on IBM MQ for z/OS with data set encryption. for more information.
