I have a client who has a few custom DNN 3 modules but wants to put them on DNN 6.   

I have looked at the desktopmodule folders, and it is a big mess.  It looks like they are compiling the code behind into a dll, which is probably because they were on 1.1 framework.   

There is no installation file, and highly doubt there it would work on DNN 6 even if it were there. 

I have manually moved the entire module folder over, and run the SQL scripts.  I go into DNN 6 and try to create a new module, and select control.  

There are quite a few .ascx files available, but I have no idea which one is considered the "main" control.   

In their old website (which I have not been able to gain host access to), there is only 1 entry per module in the dropdownlist.  

Is what I am attempting even possible, or will these modules need to be re-written? 

Thanks for your time.
