Your app expects an old version of Rails (2.3.5) from 2009/10 (which
is likely now full of security holes). For the app to work you must
ensure that you have the right version of rails and all the other gems
on the new machine. Go back to the old one and check every gem that
is used and make sure you use exactly that version (and initially only
that version) on the new machine. Once it is working upgrade it to
Rails 4.

If at all possible it would be much better to upgrade to Rails 4 on
the old server, then at least you are starting with a working system.
With current rails versions the gem version problem is solved by the
use of Gemfile and Gemfile.lock. It is not safe to have an internet
facing rails app using 2.3.5

Unfortunately it will be probably be no slight task upgrading the app.
You will probably need someone experienced in Rails to do this.
