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.
