We are in the process of upgrading our software and hosts to MQ 5.3, and some people think it should be necessary to run the software on hosts running MQ 5.1.

Is this possible?

The software is compiled on Solaris 8 using CC 5.5 and MQ 5.3.

Currently we get MQRC_CNO_ERROR(2059) when the executables attempt to connect to the local queues.

We have no problem connecting to remote MQ 5.1 queues from a machine running MQ 5.3.

Any help greatly appreciated.

No. Applications built against 5.1 will generally run against 5.3 but not vica-version. Structures increase in length (thats why most of the structures have versions in them), and the 'current version' (which is generally used during the initialization) may refer to a version which the old server does not know about.

5.3 clients can connect to 5.1 servers without problems.
