That is a super old version of rails. Annoyingly http://rubyonrails.org/
doesn't list the latest version, but rubygems.org will give you the
current version of any gem (currently 3.1.3 for rails).
ruby 1.9.3 came out just a month go or so, you might want to stick
with 1.9.2 as some gems have not (or have only just) caught up with
ruby 1.9.3

I would highly recommend to check if the gems you need works with Ruby
1.9.3 and move to this version if you can.
Performance improvements are noticeable.

For the rest...it's a very old version of Rails and I'm not sure you
will be able to migrate it painlessly, but anyways, I would recommed
you to do it pregressively. First move to the lastest 1.x version,
then move to the highest version of 2.x (I think this is 2.3.11), and
then, move to the 3.x version.

There has been a lot of changes, specially for the version 3. I'm sure
you'll find a lot of guides for moving from 2.x to 3, but I don't know
about moving from 1.x to 2.x.

Hope it helps.
