Hvordan kan jeg skifte min Rails-app fra Mysql til SQL Server i rails 4 i Windows

Føj dette til gemfile

gem install mysql2

Og dette til database.yml

default: &default
  adapter: mysql2
  encoding: utf8
  host: 127.0.0.1
  port: 3306

development:
  <<: *default
  database: development_db_name
  username: YOUR_USER_NAME
  password: YOUR_PASSWORD 

test:
  <<: *default
  database: test_db_name
  username: YOUR_USER_NAME
  password: YOUR_PASSWORD

production:
  <<: *default
  database: production_db_name
  username: YOUR_USER_NAME
  password: YOUR_PASSWORD
