Our application currently uses MQ 5.3 and we are planning to upgrade to MQ 7.
We receive/send messages from/to third party apps which also use MQ 5.3.
If we upgrade to MQ 7, will we be able to receive/send messages from/to the third party apps which use MQ 5.3 ? |

Do the apps use a MQ client or their own QM?
Either way it will work. |

If you use SSL, watch out when you ugrade to WMQ 7 as it tries to contact an OCSP server by default, to check for revoked certs.
Since this OCSP server usually cannot be connected to directly, it will hang the channel. Not a very helpful default from IBM here.
This setting in qm.ini will prevent this.

You've tested it, I assume?
I imagine there are no big problems, as long as you use all the defaults on the channel definitions.
But there is no support from IBM for 5.3 any more. |

When you migrate from version 5.3 to 6.0.0.0 or from version 6.x.x.x to 7.0.1 the QMgr on first start (re-) creates new objects which are needed in the new version.
But when you migrate from version 5.3 to 7.0.1 I am not sure, if this object creation will work properly. At least this is not tested and not supported by IBM.
I would consider, to migrate first from 5.3 to 6.0.0.0, start the QMgr once to create new version 6 objects and then migrate to 7.0.1.

Why? For what purpose? Why not go from 5.3 to 7.x?

The reason was, that I never tested this migration and did not know, if it were supported.
But the link in PeterPotkay's post explains the migration steps from 5.3 to 7. So I agree, this would be a faster and more direct migration.
But still this should be tested in on a test system.
