CF Admin > Packaging & Deployment > ColdFusion
Archives (.car)
Create a new archive file. It has to have a .car extension.
Follow the wizard to select settings to backup. Once you're done,
on the line that shows your new archive, click the middle icon to
Build the CAR file.
Once the file is created, you can load the settings into
another CF server from the same page. Under " Deploy an Existing
Archive", browse to the .car file and then click the "Deploy"
button.
