How to promote IPs from one instance of Scribe to another.

We have version How do I promote Integration Processes (IP) from our Dev, QA, ... Prod instances? For a new IP, do I copy the dts file to the next instance of Scribe, open it and specify the connections, or will it use the connections from the .dts file? 


I just took over the responsibility of managing Scribe and the IPs. Since the name of the connections to the sources are different in each instance of Scribe, how did my colleague promote these IPs? 


Our goal is to follow in implementation process where there is no human intervention for promoting Scribe IPs.
