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.
