Hi, I’d like some help to install rails 3.1 without breaking old projects that use rails 3.0.9.
If I install rails 3.1, will it delete rails 3.0.9?
I don’t understand much about it, but I think all my gems are installed in the same gemset.
Or, if it is easier, simply install rails 3.1 and update old projects to it. What I mean is, can I just follow the railscast about rails 3.1 or are there other stuff that I have to change so that old projects can work from 3.0.9 to 3.1?
