RAD can run concurrently with FCAS, so there is no need to use one or the other exclusively.
The steps documented here assume that RAD is installed and running some applications, and that you also have FCAS installed and want to migrate the RAD applications to FCAS.
To migrate a RAD application to FCAS:
1       Unload the RAD application.
Open the Application Monitor in FirstClass RAD on the administrator's Desktop. Make sure there are no sessions in use before you select the application and click Unload.
2       Remove the application from RAD.
Remove the .fcx file from the FCNS/FCRAD folder, but don't delete the file.
3       Upload the application to the FCAS Online Applications folder in Clustered Services/FCAS Config.
4       Move any related data files to the FCAS environment.
This only applies if the application connects to a file-based ODBC data source such as Microsoft Access Database. It's only necessary if FCAS is installed on a different machine from the server, but is recommended so that it's clear which data sources belong to RAD applications and which to FCAS applications.
Move the data files from the data folder in RAD (typically FCNS/FCRAD/DATA) to the corresponding FCAS folder.
5       Recreate the ODBC DSN.
This only applies if the application connects to a file-based ODBC data source. Unless the ODBC data source is embedded within the application itself, there will be an ODBC Data Source Name (DSN) associated with it.
6       Load the application under FCAS.
Open the FCAS Application Monitor, select the application, and click Load.
7       Change the extension for the installed stationery that launches the application.
RAD applications use the RAD.DLL extension on installed modules. FCAS applications use the name of the gateway (normally FCAS in single clustered environments).
To change the extension, clear "Read only" in the stationery's properties. Double-click the stationery, and the Rapid Application Installer will open. Change the extension name to the name of your FCAS gateway. Finally, select the "Read only" property once more.

If you are migrating all RAD applications to FCAS, you can make a global change to the application extensions. To do this, open the FCAS Configuration form and select "Emulate RAD.DLL".
