Migration paths

An overview of the migration paths between different IBM® MQ versions. For some IBM MQ for z/OS® migration paths, you can revert to the version you were using prior to migration. For other platforms, you cannot easily revert to a previous version.

Note: Before each new version of the product is released, it is tested for migration from earlier versions that are in support at that time. Direct migration from a version that is out of support might also work, but is neither tested nor supported. Therefore, to migrate to the latest version from a version that is out of support, you should first migrate to an interim version that was released before the earlier version went out of support.

Migration paths: IBM MQ on platforms other than z/OS

You can migrate from Version 7.0.1 or later direct to Version 8.0.

For IBM MQ for UNIX, Linux®, and Windows, Side-by-side and Multi-stage migration were introduced in Version 7.1, and can be used to migrate from Version 7.0.1, Fix Pack 6 or later. Before you use either of these migration methods to migrate from Version 7.0.1, check that your Version 7.0.1 installation is at Fix Pack 6 or later.

Prior to Version 7.0.1 Follow the instructions for your current version. For more information about where to find the documentation for older versions of the product, see Documentation for older versions of IBM MQ Direct migration is not possible. You must follow an indirect migration path, which involves migrating IBM MQ more than once.
Version 7.0.1 or later Follow the instructions for your current version. See IBM MQ product information in IBM Documentation. Introduction to IBM MQ migration and IBM MQ migration planning to the latest version on UNIX platforms, Windows, and IBM i

For IBM MQ on platforms other than z/OS, you cannot easily revert to a previous version. However, if a queue manager has not been started, you can uninstall the current version and reinstall a different version of IBM MQ. It does not matter what versions of IBM MQ are installed between when a queue manager was last started and when it is next started.
