This section gives an introduction to the documentation for customers
considering migrating to WebSphere® MQ Version 6.0.
It is not the intention of this migration documentation to cover the migration
of every possible combination of a WebSphere MQ Version 6.0 installation
and associated applications. This would not be possible as the product is
so flexible. The documentation will highlight some of the main areas that
are believed to impact a customer and give some guidance of the type of action
they will need to take to continue 'business as usual'.
Note: Prior to the installation or migration of any software, you are recommended
to make a full back of your system to ensure that you can recreate the system
to its original working environment should any problems occur.
Some general considerations
The following lists some
of the general issues to consider when making a migration plan.
- Additional migration information could be held in the Quick Beginnings
book for the platform you are installing on. You are recommended to consult
the relevant Quick Beginnings book for any migration information that could
affect the installation you are preparing for.
- Develop a backup plan in which you back up the relevant information on
the queue manager and server.
- Make sure that you read the latest readme.html and install.html files
for the products you are working with. You can find these files on the IBM® home
pages for the relevant products.
- Do you need to have the queue manager active all the time? If this is
the case, and you are unable to shut down the system running this queue manager,
you may need to consider a different migration approach. This will mean performing
the migration using the following general steps:
- Copy all resources from the server concerned to another server.
- Perform a migration on the duplicate server.
- Switch over to the new server and queue manager at a convenient time.
- Be prepared to record a number of details about the existing system topology,
including such things as the names of the queue managers and their queues,
clients, channels and so on.
- This may also be a good time to check through all existing queue managers
to see whether there are any queues that are no longer needed, and whether
there are any queue managers that are no longer required. You may also decide
that you want to keep certain queue managers at an earlier level and administer
them from a migrated system.
Supported environments

vary according to the changes to the product. Please check each of the sections
