No.
You can not *install* two versions of MQ on the same machine, except on zOS.
You can use *one* install of MQ to connect to *two or more* queue managers (regardless of where they live) from *one* application, but IF and ONLY IF you make *client* connections. And you should use a *supported* version of the MQ client libraries.
This means at least MQ v6. And certain versions of MQ v5 are *broken* and should not be used *at all*. |

thanks for your response.
i didn't ask about installing 2 servers on the same machine.
i question was if i can connect my mq client to both mq version 6 and mq version 5.3 (12) in parallel.
i'm currently (temporary until i retire the 5.3) running both 6 and 5.3 and i want to verify that our client can work with both in parallel.
thanks...

Yes, you can connect your MQ client to the supported MQ versions in parallel using correct client libraries....
As mentioned by Jeff...

Please let us know the version details of MQ server (5.3 and 6.x).
Check WebSphere MQ Clients redbook for more details about client connections to QM's... |

Yes indeed....
Is your client using v6 libraries?!
how exactly have you configured the client connections to the server ?! |

MQ Client <-> MQ Server compatibility is usually very good across different versions. Obviously there may be changes in protocol from version to version, but the ends will negotiate the common highest level and provide the functionality at that level. eg. MQ 7.0 Server can talk to MQ 6.0 Client but it won't provide the new 7.0 features like read ahead, async put, and conversation sharing to name a few.
