Is there a reliable guide online for converting a Rails 2 app to Rails 3?

I have a Rails 2 application and I'm looking into converting it to use Rails 3.

Does there exist somewhere a coherent, accurate, and up-to-date text document (not a screencast) along the lines of "How to Convert a Rails 2.x Application to Rails 3"?

Or even just, "A General Guide to Converting an Application from Rails 2.x to Rails 3 Covering the Issues You'll Need To Consider and the Common Pitfalls".

(The problem with screencasts and their transcripts is that they're very difficult to update, so th开发者_运维问答ey don't get updated and they rapidly become unreliable.)

A great guide is the 3-part screencast series on Railscasts by Ryan Bates

No, because every application is different. The Rails 3 Upgrade Handbook will get you started, as will the rails_upgrade plugin.
