/**
* Perform a migration of this module.
*
* Make sure you rollback any changes if your migration fails!
*
* By default, the migrate routine just runs the migrations in Doctrine for your models, based on the version of
* this module and the version registered in the database.
* If that's all you need for your migrations, you don't need to override this function.
* All models in the directory of your module will be migrated.
*
* You do not need to override this class if you are not adding additional functionality to it.
*
* @return array | NULL Array of failures, or NULL if everything is OK
