Install ColdFusion MX for J2EE Application Servers on a test server that has your J2EE application server installed.
Move the directory with the application under the cf_root directory on the test server.
Test the ColdFusion MX application on the test server. Using a source control system, make any necessary changes to the application. Ensure that you test all application features under load, not just with a few users.
Tip: A number of testing applications are available for download from the web. For more information, see the Support section of the Macromedia website (http://www.macromedia.com/support).
If you encounter problems that do not seem to be related to the code, ensure that you are using comparable administrator settings. For example, Java Virtual Machine (JVM) settings are handled by your application server, not ColdFusion MX. For more information, see "Differences in the ColdFusion MX Administrator," in Chapter9.
