Migrate schema updates onto existing schema
I suggest that you use a tool such as Liquibase or Flyway which is designed to manage such schema changes in a database and keep the configurations consistent and known.

There are other tools available and they usually have plugins to maven, Puppet &amp; Chef etc...it'll come down to a google search and personal preference.
