From his article :
“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.”
