[flexcoders] How to change the data access option in an existing Flex project

[weichungwang]

Does anyone know how an existing Flex project's data access option can 
be changed from "Basic" to "ColdFusion Flash Remoting"?  The project 
was initially developed using the basic data access option.  But now it 
needs to access data via Coldfusion Flash Remoting.  
 
Thanks
