Upgrading Rails app from Ruby 1.8.7 to 1.9

Now that WebFaction has the 1.9 version of Ruby installed, I'm wondering what the best way to upgrade my existing app to it is. Are there steps I should run on the existing app, or would I be better served by just creating a new Rails 3.2 app on 1.9 and transitioning my websites over to those?

Any advise is appreciated.

As far as we are aware, the most straightforward and safest transition is to create a new Rails application and migrate your existing application to the new version. In many cases, you'd be upgrading the actual Rails version in addition to the Ruby version, so having to re-work some of your structure and code would be necessary anyway. This method also allows you to test the application before taking it live.

Thanks. I was considering trying to move my existing Rails 3.0 app up to 1.9 before making the jump to 3.2, but if this is the path then I'll just do them together. Appreciate the confirmation.
