You can use incremental BAR file deployment or complete BAR deployment to deploy your solution.
Use incremental BAR file deployment to deploy applications, libraries, message flows, message model schema files, or other deployable objects incrementally to an integration server.
To completely clear the contents of the integration server before the BAR file is deployed, use complete BAR file deployment instead.
If you run a complete deployment of a BAR file, the integration node extracts the deployable content of the BAR file and sends the contents to the specified integration server, first removing any existing deployed contents of the integration server.
Use a complete BAR file deployment to deploy applications, libraries, message flows, message sets, or other deployable objects to an integration server.
To merge the existing contents of the integration server with the contents of the BAR file, use incremental BAR file deployment instead.
