This is a constant struggle for me. It took about 3 years, but I had most of our company using google docs and not working locally much. Then a critical mass of newcomers came and the IT department decided we should move away from google docs and so provided a file server. A year later, a few people of us are stubbornly using google docs but 80% of our files are scattered across the fileserver and desktops. And you can be sure that whatever you find on the fileserver is not the latest version.

While I’m on a rant, the same people refuse to use commenting features and instead add red text and text boxes all over the place.
