ColdFusion 5.0 code comaptibility with ColdFusion MX7

Hi,

I have an application written in ColdFusion 5.0 and using the Fusebox 3.0 framework. I have a ColdFusion MX7 license and would like to get this CF 5.0 code work with ColdFusion MX7. I have just started and have managed to get the login page after changing a function syntax, but am still not able to see the rest of the application.

Please advise on the feasibility of getting the CF 5.0 code work with ColdFusion MX7.

Thanks,
Purns
