Migrating from earlier unsupported releases of IBM MQ for z/OS

IBM MQ for z/OS Version 9.2.0 supports migration of queue managers that previously ran at IBM MQ for z/OS Version 9.0.0 or later.

Migrating from a release earlier than Version 9.0

Migrating from a release earlier than Version 9.0, for example, Version 8.0 or IBM WebSphere MQ for z/OS Version 7.1, requires a multi-stage migration.

Firstly, we must migrate the earlier release of IBM MQ to IBM MQ Version 9.0 or IBM MQ Version 9.1, following the instructions given in the documentation for that release. For more information about where to find the documentation for older versions of the product, see Documentation for older versions of IBM MQ

We can then migrate to IBM MQ Version 9.2 following the instructions in Migrating IBM MQ for z/OS - order of tasks.Important: Ensure that the system is stable at Version 9.0 or Version 9.1, before migrating to Version 9.2, so that we have a system to revert to, if necessary.
