Divestiture question

We are in the process of selling a portion of our company. We will need to move their data to it's own Windchill server. The new company will not be purchasing all the modules that we own, specifically they will be dropping ESI, PartsLink and ProjectLink. Has anybody had any experience with either of those two scenarios

• Splitting Windchill - cloning and removing data, or another approach that will retain as much fidelity as possible, Parts, CAD, Doc, Changes, WF, etc
• Removing modules from Windchill - Did you ever implement a module for Windchilll and later terminate support for that, what did you have to do?

Thanks,
Steve D.
