We currently run WorkGroup PDM and so far this has been go enough. However I'm starting to wonder if it might be time to switch to Enterprise. What I'm looking for is something that can show me the difference between the two. Like how is ownership of files handled? How are revisions handled? How are release states handled? I'm not looking for a sales pitch (which is what a VAR will give me) I'm trying to figure out how the transition is going to work and what kind of learning curve I'm looking at. I also would need to be able to tell my boss (a non-user of SW) that now we can do A but if we upgrade we can do B.

Any help would be great, point me to a document, a quick break-down, whatever you got.

Thanks in advance for all your help guys...
