Can we migrate a qmgr from windows to AIX/UNIX

by taking its configuration backup(using MS03 Support pack for old versions or dmpmqcfg commad)

Prevously one of the qmgr is running in windows(V7.0.1.13), we have taken that qmgr configuration backup using (MS03 support pack).

Later we installed IBM MQ (v8.0.0.4) in AIX server. We created a qmgr (with same name which running in windows) and restored that windows qmgr configuration backup in AIX qmgr.

You've done it once so why are you asking whether it's possible?

There are some things that won't work in this case.

For example where there is filename + path in the config. i.e. the path to where you have your SSL/TLS key files.

It worked before because it was Windows to Windows.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

After migration you need to consider all the new functionality of V 8 especially in the security area.

Have fun

Before restoring the defs on to the new qmgr you should review every object definition, particularly channels and SYSTEM objects. Check that cluster receivers have the correct host / port. Check receivers, to ensure the remote qmgr sender channel has the correct host / port. Check object authorization profiles and channel auths. Check channel SSL if it is being used. If the qmgr is in a MQ cluster, remove it from the cluster before migrating it.

I did it but, i just want to know. It is not a cluster qmgr, It is a circular loggin qmgr. While restoring backup, we created linear loggin qmgr in AIX and restored that configuration backup in AIX qmgr.

I cross checked every thing, Sender channels and receiver channels are working fine. The problem is with MQI channels. We are getting two connections per ip, one is incomming and another one is outgoing.

The problem is with putting applications. They are able to connect and put messages, after some time the connection goes to idle and disconnect. But their is no problem with getting applications, they are connecting contineously. At qmgr error logs we are getting AMQ9209, AMQ9999 and sometimes we are getting AMQ9207

Getting applications seem to have bad practice. They should be connecting once and disconnect only when they are done. Not connecting constantly. They should also be reconnecting on connection broken. If that is the case you may also need to run a very small keep alive interval with the correct Adopt New MCA to avoid running out of connections...

Have fun
