You didn't provide enough information about what you were previously using on the old server. What version was the old server running, what sdk is the cold fusion application using. I'm assuming that when you try to run the application, you are getting errors, you might want to provide those.
The old server was using Crystal Reports 9. As far as SDK that is being used now....I believe the answer is 3.5...but I don't know how to be definitive on that answer. The only error I get when I try to run a report from a CF app is Page 404 error.
404 error means page not found, which does not say that there is an error. Without you understanding what the code in the Cold Fusion application is, there isn't much anyone is going to be able to do for you. There are too many different ways they could have been viewing the report.
