If I were consulting to this project, I think the first questions I would ask are:
* How many producers and consumers are there for this data feed, and are they all under your control?
* Is the data completely transient or do you have persistent data that needs to be migrated?
* Is the data format well documented and understood? How complex is it?
* How good is your test suite? If you break anything, how will you know (and what are the consequences if you don't)?
* What are you hoping to achieve by the change in technology? If there are problems that need to be fixed, is a change in technology going to help fix them, or is it just going to distract from the real issues?

I wanted to know about the possible risks that one might encounter while deciding to migrate the messaging format from XML to JSON in a data exchange environment. What criteria one must take into account before making a decision to pursue such overhaul? Factors such as: complexity of data structures, validation requirements, security, etc. How would a system architect go about such analysis?
