How to manage Engineering using EPDM and Network Drives?

I am currently an EPDM Admin for a large company (approx 100 users) and have some users using EPDM with some users still using Network Drives (probably 50-50) to manage their SolidWorks files. There are many users that use Pack-n-Go to pass models if using the 2 different methods. We also have alot of 3D PDF's and eDraws being created to communicate design info to non-SolidWorks users. Does anybody else have the same situation? If so, do you have a good process for managing this type of collaboration?

Thanks, Todd
