To update your IDM WAR file:
Run the ConfigUpdate utility in the User Application install directory by executing configupdate.sh or configupdate.bat. This allows you to update the WAR file in the install directory.
For information on ConfigUpdate utility parameters, see Section 5.6.14, Configuring the User Application or Section 5.7.10, Configuring the User Application.
Deploy the new WAR file to your application server.
