Hi @Ani ,
In addition to the information provided by @Aaron, take a look at this blog post I wrote a while ago:
It gives some practical guidance on how to map the various exchange types from Rabbit onto Solace.
Topic exchanges are the most natural to port to Solace and nicely map to Solace topic with a queue subscribed to it.
Hope this post helps. Let me know, if you have further questions.
Cheers,
Christian
