It is recommended you use RVM. Then you can switch between Ruby versions. You will still have to tell the Gemfile to use ruby '2.0.0'
Rails Installer - How to update just ruby from 1.9.x to 2.0 +?

Question
I installed with railsinstaller with Ruby version 1.9.3
Can I simply change my Gemfile to specify a different version of Ruby, or does updating Ruby not work like gems? I don't want to break anything during my fiddling.
I wish to avoid:
1) having to reinstall railsinstaller alpha with 2.0.0
2) downloading a separate package like RVM
3) having to do backup operations with files, databases, etc.
Gem updates can bypass all 3 obstacles very easily. Is this also possible with Ruby itself?
