Migrate4j is a migration tool for java, similar to Ruby's db:migrate task. Unlike other Java based migration tools, database schema changes are defined in Java, not SQL. This means your migrations can be applied to different database engines without worrying about whether your DDL statements will still work.

This version adds improved usability (simplified syntax), additional schema changes and support for more database products. While migrate4j does not yet have support for all database products, we are actively seeking developers interested in helping fix this situation.

Visit for more information on how migrate4j can simplify synchronizing your databases. To obtain migrate4j, go to and download the latest release. For questions or to help with future development of migrate4j, email us at migrate4j-users AT (replacing the AT with the "at symbol").
