Upgrading to Rails 3.2 -If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 3.1 in case you haven't and make sure your application still runs as expected before attempting to update to Rails 3.2.

Rails 3.2 requires at least Ruby 1.8.7 Rails 3.2 requires Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially and you should upgrade as early as possible. Rails 3.2 is also compatible with Ruby 1.9.2. -TIP: Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails. Ruby Enterprise Edition have these fixed since release 1.8.7-2010.02. On the 1.9 front, Ruby 1.9.1 is not usable because it outright segfaults, so if you want to use 1.9.x, jump on 1.9.2 or 1.9.3 for smooth sailing. +TIP: Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails.
