NOTE This screencast covers an unreleased version of Rails 3 run from the source. Rails 3 Release Candidate 1 has been released and we’ll update this screencast when the final version is available.

For several months people have wondered, “Where can I download a video that features a developer stumbling through an upgrade of a Rails 2 app to Rails 3?”

I’m proud to say that an answer is now available!

In only 25 minutes, I convert my news screenshot site from Rails 2.x to Rails 3 (prerelease, from source).

It features the newest bundler (0.9.0.pre), Jeremy McAnally’s rails-upgrade script, new routes, Arel-based ActiveRecord queries, and more.

Stay tuned for the explosions at the end!
