title: Should I upgrade from rails 2.3 to 3+ or wait until rails 4 is released and upgrade then?
body: <p>I'm about to start working on porting a company's old rails ap from 2.3/1.87 to the most recent version of rails. Should I wait for rails 4, or should I just to 3.2?</p>
  
  <p>We're going to take the opportunity to make sure there is full test coverage, and there will probably be some rewriting involved as well. The first goal is to make sure all current functionality is operational.</p>
  
  <p>We want as much of the current codebase as-is to work under the most recent version of rails. We will rewrite any parts that don't.</p>
