We are developing a multi-site page that will function something like Craigslist with many sub-directories for different cities. We have a few plugins in place and activated for the network. We are using a "cloning" plugin to duplicate the cities quickly. It works very well and enables us to maintain consistency in appearance with the themes, fonts, plugins, etc.
Is there a way to update an entire multi-site network quickly, and painlessly? For example, we may need to make some changes in how one of the plugins is configured. Is there a way to make that change network-wide without laboriously going through each and every city/sub-directory one by one and updating the specific plugin? (hope this question makes sense).
