Additional Requirements
An Integrity Lifecycle Manager server configured exclusively for configuration management does not support change packages.
If workflows and documents, and configuration management are running on different servers, then the im.user, im.server, and im.port properties must also be set in si.properties to identify the Integrity Lifecycle Manager server that is to be used. For more information, see “Source Configuration Management Properties”.
