Setup RVM to use a different version of Rails
Raw

# Assuming you have ruby (say 2.0) installed along with Rails (4.0)
# If you now want to set up Rails 3.2 as well, (for example to connect to SQL Server databses, which Rails 4.0 can't do)
# Set up rvm to use a different gemset (which in this case we will call Rails3.2)
rvm use ruby-2.0.0@Rails3.2 --create
# install Rails 3.2 in that gemset
gem install rails -v 3.2
# list the available rvm gemsets
rvm gemset list
