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.
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.
From / To | Version 7.R | Version 8.0 |
---|---|---|
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.
