q 2.3.x upgrade - current status

hi

im running a 2.3.x rails app with Prototype, Scriptaculous, and RJS etc.

i want to upgrade the app to 3.1

im not sure about which way to go.

  1. replace scriptaculous with jrails, then replacing all rjs in favor of jq-js,

  2. generate a new rails3 app and copy over the views and use:

https://github.com/rails/prototype-rails

  1. other ideas?

thx
