- Install WMQ on Linux
- Create a script describing all the WMQ objects on Solaris using the method relevant for your platform (or get the script you create for Solaris out of your repository)
- Edit the script to reflect the new server
- Run the script into Linux
- Recreate / edit all connections to reflect the new server

Don't forget to save/export/copy to tape (or other) any messages in queues. These will need to be imported to queues on the new plaltform.

Hi,
Incase if i have any messages in queue and if i use saveqmgr to dump all the MQobjects will message get store in it(I think it wont but need confirmation) and should i use qload to copy the messages. If i copy the messages how can i restore them on same queue. |

You shouldn't rely on us for confirming things.
You should confirm them by reviewing the documentation and then running tests. |

Try it and see. Much more reliable than taking the advice of a bunch of unaccountable strangers on the Internet.

If you want. There are a number of possibilities.

Seriously? You're asking how to restore the messages onto a queue, i.e. load them back onto the queue? Think for a moment about why the author called the utility "q load".... 
Alternatively you can use the same method you used to copy the messages off to copy them back on. Radical I know, but I'm just that kind of dangerous thinker.

In theory all queued application messages are owned by the application support team, not the MQ administror, and it is the app team responsibility to process / clear / copy the messsages for the migration.
The easiest solution is to ensure that all transmission queues and application local queues are empty at the time of migration.
Copying messages may actually cause problems, eg. with CCSIDs and Encoding.

Dealing with messages left in queues needs to be part of the plan for any migration.
