We are planning to migrate to MQ 6.0.2.4 from 5.3 CSD10 on AIX.While going through the migration steps, I came across the below task
"Uninstall WebSphere MQ and any WebSphere MQ service updates"
As far as I know, migration means upgrading a software to the latest version by just ending the component's activity without uninstalling the existing version.Hence, I was bit worried about if my understanding of migration itself is wrong. Is ending an activity, uninstalltion and installation called migration? Do we have to uninstall MQ before installing the new version |

On some platforms, previous versions have to be uninstalled as newer code cannot be blown over the top of existing code, hence the statement. I don't think IBM would put it in the documentation on a whim.

Hi,
Please follow the document for Websphere MQ V6.0 quick begining for Aix
WebSphere MQ is supplied as a set of filesets that are installed using AIX’s
standard installation tools. The procedure below uses the system management
interface tool (SMIT), but you may chose to use installp, geninstall or the
Web-based System Manager. you must install at least the Runtime, and Server components.
1. Log in as root.
2. Insert the WebSphere MQ Server CD-ROM into the CD-ROM drive.
3. Enter the following command to mount the CD-ROM:
mount /cdrom
4. Select the required smit window using the following sequence:
Software Installation and Maintenance
Install and Update Software
Install and Update from ALL Available Software
Alternatively you can use a fastpath command (smitty install_latest),
however this does not give you the opportunity to install the language filesets.
5. Click List to display the input device or directory for the software, select the
location that contains the installation images.
6. Use the SOFTWARE to install field to obtain a list of available filesets, and
select the filesets you want to install. Ensure that you include the appropriate
message catalog if you require a messages in a language different than that
specified by the locale selected on your machine.
7. Make sure that Include corresponding LANGUAGE filesets? is set to yes.
8. Change Preview new LICENSE agreements? to yes and press Enter to view
the license agreements.
9. Change ACCEPT new license agreements? to yes and press Enter to accept the
license agreements and install WebSphere MQ.
create a Queue Manager and start it to verify the installation |

Good start, but the rest of your post is applicable to installing, i.e. on a 'clean' server, whereas pshan81 is migrating to V6.0, in which case, the following is applicable:

3. Uninstall WebSphere MQ and any WebSphere MQ service updates.
4. Install WebSphere MQ Version 6.0 by following the tasks set out in the book. |
Also from the QB.

I am new to MQ,
as i was going through the documents...IBM strongly suggests to uninstall the older version and reinstall the new one. Then migrate the file sytem to new version by starting the queue managers.

For MQ, u r understanding of Migration is correct (anyone,please correct me if I am wrong) i.e, uninstall and install the new one. Most of the times, for other softwares we upgrate the older version to the new one. Upgration ways may vary with the type of filesets that software build on.
In MQ they will vary based on the platforms too..For more better understanding. Please refer to the IBM MQ info center

I expect it is called "migration" because your data is protected. When you uninstall the executables and related files, your queue managers with all their object definitions, as well as your message data, remain intact.
The first time you start your queue manager, the existing object definitions will be updated (migrated) to be compatible with the new executables.
I found it confusing, too! Just my take on it. |

I agree with exerk this is not a fresh installation
so the MQ installation of V5.3 has to be uninstalled
a. Log in as root.
b. Use the endmqm command to stop all running queue managers.
c. Stop any listeners associated with the queue managers, using the command:
endmqlsr -m QMgrName
d. To check that you have stopped all of them, enter the following:
ps -ef | grep mq
Check that there are no processes listed that are running command lines
beginning amq or runmq. Ignore any that start with amqi.
If you are migrating from a WebSphere MQ server installation, uninstall the
following WebSphere MQ Version 5.3 filesets:
mqm.Client.Bnd
mqm.dce.Samples
mqm.dce.Server
mqm.Server.Bnd
If you are migrating from a WebSphere MQ client installation, uninstall the
following WebSphere MQ Version 5.3 filesets:
mqm.Client.Bnd
mqm.dce.Samples
Other WebSphere MQ Version 5.3 filesets will be overwritten.
Install WebSphere MQ Version 6.0 by following the tasks set out in the book. |

Thanks all for your inputs.
Saneban, Is it fine to uninstall only the file sets you have highlighted? |

Follow the Quick Beginnings for the platform (AIX in your case) as posted on the Info Centre, as that is the most up-to-date information; go HERE to find it.
