Aspects of an integration between Creo Illustrate with Windchill

Hi, i am trying to get kowlegde about the aspects of what an integration of Creo Illustrate 4.2 and Windchill will mean regarding the actual work to set up the integration and what I need to consider regarden the environment/set up my company has in Windchill.

Is it straight forward or very much to consider/think of? What are those thing?
