I have a rails application created with an earlier version of Rails. I  
would like to take benefit of new features in Rails version 2.2.2 Is  
there a way or command by which the configuration settings of the  
existing application can be updated as per needs of newer version of  
rails? I understand that making any changes to the code would be my  
responsibility.

Just run rake rails:update in your application folder.

I have done it for our app and it was pretty painless.
