title: Rails 2.1 and Rails 2.3 sharing the same database
body: <p>We have an admin application used to manage member data and it was built in 2.1, has been running for about a year. Now that all inputs and data massage is done, our client wants to start building member site, members will have access to data the administrators have been inputting.</p>
  
  <p>Here's the question, should we start a new Rails app hooked to the same admin database or should we create a new Rails app in different db with master-slave settings? The good thing about creating a new Rails app is obviously taking advantage of the new version, which we like. Or ..maybe just build the member site in the same admin app?</p>
  
  <p>THanks,</p>
