There is only one trap, or one savior for your move to Creo. Your organization will have to decide if top-down design will be allowed or not. The idea is that files are dependent on each other (parts tied to assemblies) or if all files must stand on their own.
If top-down design concepts will be allowed, you will want some very strong safeguards in how to use this functionality. In this case, you will want to understand a "master model" or "skeleton" concept.
