Hi,
I am looking at MQ v7 pub/sub options.
I was wondering if it is possible to define a topic so that each message arriving on a particular queue is published to this topic.

This question is originating from my requirements to migrated Pub/Sub setup from Message Broker to MQ v7.

We have a setup where application sends a message to a queue with a customer header that defines a topic name and event name.

There is a message flow deployed that reads the message from the queue and forms a topic using the values from custom header and publishes it.

Subscribers are defined on the broker to send message to specific clustered queues.

The subscriptions are straight forward to migrated from btoker to MQ.

But challenge is on Publish side. I have two options:
1. Change all the publisher applications to specifically publish their messages. This may be very difficult to get done in short term.
2. Continue to use Message Broker or another component that reads the messages from the published queue and then form the topic to publish the message - this is not a true pub/sub.

Is there any way that the point 2 can be achieved at Queue Manager level using Topic definition?

I know, I might be shooting here in the dark, but if there is any way, it would greatly reduce the turn around time in my project.

Thanks a ton in advance!
