Wukong-migrate, inspired by rails, makes updating database schemas and settings painless and straightforward. Utilizing your app's models and the settings discovered by Wukong-deploy, only a simple migrate script is required to be able to make changes to databases. Keep your databases in sync with your app code more cleanly and with less effort.
