Nova Fabrica Rails 3 to Rails 4 Cheatsheet

Upgrade guides

I think this is a good place to start. It tells you the first steps, it's not exhaustive but it gives you a great starting point. http://railscasts.com/episodes/415-upgrading-to-rails-4?view=asciicast

Another 'getting started' guide: http://pivotallabs.com/rails-4-upgrade/

When running 'bundle install', I randomly get this error:

Gem::Package::FormatError: corrupt gem (Gem::Package::TarInvalidError: tar is corrupt, name 
contains null byte) in /Users/kmtrowbr/.rvm/gems/ruby-1.9.2-p290@hitrecord/cache/haml-3.1.2.gem
An error occurred while installing haml (3.1.2), and Bundler cannot continue.
Make sure that `gem install haml -v '3.1.2'` succeeds before bundling.

I am using RVM, I started troubleshooting by removing the 'corrupt' file, eventually progressing 
all the way to doing an 'rvm implode' and reinstalling everything, including upgrading rails 
1.9.2 to the newest version (p290) and upgrading bundler itself to 1.0.20.
