guide to moving Rails 1 app to Rails 2?

Are there any guides available on what must be done to move an app written with Rails 1.x to the latest Rails 2.x?

I'm having trouble finding such a thing in Google.

Thanks for any pointers!

I once read that, if you’re upgrading from a release that is several releases or a major release behind your target version, i.e., 1.x to 2.x, you should upgrade gradually. Say you’re on 1.2.2.

1.2.2 → latest 1.2.x release latest 1.2.x release to latest 2.0.x release latest 2.0.x release to latest 2.1.x release latest 2.1.x release to 2.2.x (when it becomes available)

With each step, also upgrade plugins to a release that most closely matches the Rails release if possible.

Such an approach should minimize the breadth and depth of changes required of your code, Rails and plugins.
