Upgrade to the latest Ruby you can first, and then upgrade Rails. It's a good idea to upgrade Ruby and Rails separately. Rails generally stays close to the latest released Ruby version when it's released: Do yourself a favor and make sure your test coverage is good before you start an upgrade. In the case of a Rails upgrade, that will mean every single piece of functionality in the application. If you don't have automated tests that exercise the bulk of your application, you'll need to spend time manually exercising all the parts that have changed. The best way to be sure that your application still works after upgrading is to have good test coverage before you start the process. You need to balance several factors: the need for new features, the increasing difficulty of finding support for old code, and your available time and skills, to name a few.
