All,
Is there a way to rename a queue manager?
Regards,

Not that I know of.
The way I do it is to 'dump' the queue manager definitions to a flat file (Saveqmgr support pack). Then I delete and recreate the queue manager with a different name and then pipe the output file from the saveqmgr as input to a runmqsc to the new queue manager. |

There is an easy workaround if you are willing to try it.
It will not really rename the queue manager but make it addressable with an other name.
Create an alias for the queue manager
define qr(alias) rqmname(old qmgr name)
That should do the trick. You can now address qmgr alias on that box.
The other work around would be to create an alias on the sender box.
Check out the manuals. They explain about alias in the Queue Remote and intercommunication sections.
Of course like I said this does not truely change your environment.
In dev on a unix box and NOT on windows(because of entries in registry) you could try and rename the path (/var/mqm/qmgrs/<qmgr>) and (/var/mqm/log/<qmgr>) while the queue manager is stopped. Then you need to edit /var/mqm/mqs.ini and adjust the information on the renamed queue manager. Then run dispmq and see if this works for you when restarting the qmgr with the new name.
Now if your OS is OS390 I wouldn't have the slightest idea

Well that's only for 'addressing' the QueueManager from another QueueManager in a remote queue definition, NOT for addressing the QueueManager itself on the box it is running on (i.e. MQCONN)
This is the general misconception of the term QueueManager alias...

This is indeed what QueueManager aliases are all about.

be sure to make a backup first and do this in a development environment

actually this 'rename' trick on OS390 is far 'easier' if there is anything easier on OS390, as QueueManagers run in subsystems and you can 'alter' the addressing of the 'subsystem' underneath.
Have not done this myself, but samples exist on the vienna list archive.
