Question

Im considering upgrading a rails 2 app to rails 3 for a number of reasons (rails 3 features, certain plugins require rails 3 etc.)

Obviously ill have to update/grade some of the plugins as well. But concerning the code itself, should there be any compatibility issues when upgrading to 3? I know rails 3 changes a lot of helpers and syntax to make things easier, but do the older and more complicated ways still work (ex. gems in envioronment.rb, not Gemfile).

Also, anyone know a good tutorial on how to do it?
