I recently upgraded a rails 1.6 project to 1.2.2. I looked around
rubyonrails.org and the apis and didn’t find any reference on how to
upgrade. I searched the web and found that “rake rails:update” should
be called so I tried that with no luck. I then started poking around
the project files and found the RAILS_GEM_VERSION property in
environment.rb and changed it to 1.2.2 and ran rake again which
appears to have worked.
Are these the proper steps to take when upgrading an existing Rails
project? Does anyone know where this is actually documented? I’m new
to rails and I’m assuming I overlooked some release notes or upgrade
guide that you typically find bundled with a release.
