Overview of multiple installations

A description of multiple installations together with the hardware and software used in this scenario.

About this task

An important aspect of this feature of multiple installations of IBM MQ (multi-install) in the same host, is that this type of installation does not require that the queue managers and applications on the earlier version of the product do not need to be stopped when doing activities with the later version of the product.

That is, the installation of the later version of the product does not affect the running of applications on the earlier version of the product. This is helpful when you try to do a multi-stage migration of the queue managers on the earlier version of the product to the later version.

For this scenario, Version 8.0.0 is used as the earlier version of the product, and Version 9.1.0 is used as the later version of the product.

Use a Long Term Support version of IBM MQ

This scenario uses an LTS version of IBM MQ for the later version of the product.

If we are using a Continuous Delivery ( CD) version of IBM MQ for the later version of the product, we must uninstall the CD version we are using, for example, Version 9.1.1, before you install a later version, for example Version 9.1.5. For more information, see Migrating from one Continuous Delivery release to another.
