First I assume you are using a source control system (git for
example). If not then start with that.
Then I suggest writing tests before making any changes, otherwise you
will not be confident all is working. Then upgrade to rails 3 only
changing what needs to be changed to make it work (ie passing tests).
Then proceed with enhancements and re-factoring.
