Is it possible to upgrade to v12 on our staging area only, just as a way to test things out? There are some features in v12 that I'm curious about--don't know if they will help with a new project we're working on or not. In an ideal world, I'd like to upgrade our staging area to v12 first, play around with the new toys, and then schedule an upgrade for the production site accordingly after I know what to expect.
Doable?
