First, I'd recommend doing this in steps, first upgrade to Rails 2.0, then 2.1, then 2.3.5 Why? Rails 1.x to 2.0 was a pretty big change, for some apps 2.0 to 2.1 was even bigger because of some subtle and significant changes to ActiveRecord. So I'd do each step, and pause to make sure your tests are working. You DO have tests don't you? Googling for rails upgrade, flushed out this article on the first step, more specific searches are likely to find articles on the others: http://www.sitepoint.com/blogs/2008/01/25/upgrading-to-rails-20-a-recipe/ It includes a pointer to a rake task written by Geoffrey Grossenbach (of Peepcode fame) which find stuff deprecated in 2.0. Recent versions of Rails have rake tasks to aid in upgrading e.g. in 2.3.5 rake rails:update # Update both configs, scripts and public/javascripts from Rails rake rails:update:application_controller # Rename application.rb to application_controller.rb rake rails:update:configs # Update config/boot.rb from your current rails install rake rails:update:generate_dispatchers # Generate dispatcher files in RAILS_ROOT/public rake rails:update:javascripts # Update your javascripts from your current rails install rake rails:update:scripts # Add new scripts to the application script/ directory I don't recall if 2.0 had these, or at what point they were introduced.
