The difference in the architecture Coldfusion and ASP.NET are the only limitation that proves to be problematic in this case. A way to migrate Coldfusion to ASP.NET is described here
and it proves to be a lot of work. Another way is to use some of the specizlized software that is migrating coldfusion to asp automatically. We haven`t tested integrating coldfusion to Sitefinity because the approach is the same as creating a new asp.net controls based on the same controls created in another platform and this may prove to be much effort if the application is very big.
