  1. Documentation
  2. Change Log

A database migrations engine for the Yii framework. It comes in the form of an extension which can be dropped into any existing Yii framework application.

It relies on the database abstraction layer of the Yii framework to talk to the database engine.

It’s largely inspired on the migrations functionality of the Ruby on Rails framework.



  • Yii 1.0 or above
  • Extract the release file under protected/extensions
  • Follow the instructions in the README.textile file to install the extension.
