Information Analyzer migration issues

[grasshopper]

Hello,
We are migrating our IA assets from our DEV environment(ServerName1) to our SIT environment(Servername2). We are able to migrate all the assets successfully w/o any issues. We checked the import (SIT) location and we area able to fin every location.
When we open go to Binding and Output tab after opening a rule set, the DSN(Data Source Name) are still showing that of DEV environment. The server and everything under the DSN are showing configuration of DEV environment. We know we can delete each one of these and create new DSN pointing to SIT but is there a way we can update/modify DSN automatically so that human error is minimized?

Thank you, :D
