We are currently on AIX 5.3 and MQ 6.0.2.3.
We are planning to migrate to a different data center.
What is the easiest way to migrate MQ to the new server which is also on AIX 5.3
just copy over /var/mqm and reinstall ,
Or is there any other way of achieving it.
Also we need to migrate MQ Workflow and Broker as well.
Any help is appreciated. |

I suppose the easiest way is to physically move the server to the new location. But I gather that you have some other requirements.

If by this you mean install WMQ on the new server, then copy /var/mqm it should work. If it was me, I'd create a new queue manager with the same logging parameters on the new server to set up the ini files and the path, then overwrite that with the backup.
Alternatively you could backup the queue manager with MS03 and move it that way - possibly cleaner. I'd do that myself unless there were messages in the queues when you moved them.
Same with broker - install it on the new server then redeploy all the flows. You could just move the database but it's cleaner to do it through proper methods.

If I do a file system copy with out installing on the new server will that work ?(/var/mqm, /usr/mqm)
Or
No matter what, I have to install MQ and then configure as you mentioned. |

It might run, but the OS won't think that WMQ is installed because it's not been through SMIT. So when you come to apply patches etc that's going to fail. You'll also need to manually adjust the kernel parameters for WMQ that would normally be done by the install script.
Look at it this way - if you were moving WMQ from one Windows machine to another, would you just copy C:/Program Files/IBM from one to another? Would that work if you were moving Word?

Notes is a law unto itself, and should not be confused with real software
