This topic describes the installation of the WebSphere message
migration utility. It also describes the steps that are necessary before the
installation.
Before you begin
Before you install the WebSphere message migration utility ensure
that you have backed up your embedded messaging queues on WebSphere Application
Server Version 5. For details of backing up queues refer to the
WebSphere MQ System Administration Guide. This guide
applies to backing up WebSphere MQ queues but can be used to back up your
embedded messaging queues.
Note: If you back up a WebSphere Application Server
Version 5 queue before migration and then reinstate the whole queue and start
migrating the same queue again, you will get two copies of the messages in
WebSphere Application Server Version 6.
