A J2EE application might be replaced in order to upgrade and maintain the J2EE application, after the system operations begin.

Normally, to replace a J2EE application, you must stop the J2EE application that is running on the J2EE server, delete the application, and then import and deploy a new J2EE application.

For details on the normal J2EE application replacement procedure, see 5.6 Replacing J2EE applications in the uCosminexus Application Server Operation, Monitoring, and Linkage Guide.
