The IDD configuration file (IDDConfig.xml) is an XML document that can be modified in the IDD Configuration Manager or exported and edited manually.
To edit the configuration for an existing application:
Export the IDD application to a ZIP file.
Extract the application ZIP file.
Edit the IDD configuration file (IDDConfig.xml).
Import the edited configuration file directly to replace the one in the database (Import IDD Configuration only). Alternatively, the IDD application can be re-zipped and the full application can be imported to replace all the files for the application (Import Complete IDD application).
