Rails 3.1+ can handle Multiple Connections
Create model to handle the old connection. For this example we've pivoted to the new database and will be connecting to the old database
Create an database setting in your database.yml
For the purposes of this example we're going to call it OldModel
Copy your current models to a new subdirectory in /app/models/

| # This file is auto-generated from the current state of the database. Instead | |
| # of editing this file, please use the migrations feature of Active Record to | |
| # incrementally modify your database, and then regenerate this schema definition. | |
| # | |
| # Note that this schema.rb definition is the authoritative source for your | |
| # database schema. If you need to create the application database on another | |
| # system, you should be using db:schema:load, not running all the migrations | |
| # from scratch. The latter is a flawed and unsustainable approach (the more migrations | |
| # you'll amass, the slower it'll run and the greater likelihood for issues). |
