Description copied from interface: Migrator

Run the migration.

Migrators should log all output to the given PrintWriter. This is the log that is created by RunMigrators. It is an autoflush writer.

Migrators should return true if they successfully completed migration and false otherwise. It is the migrator's responsibility to log failure reasons to the log.

Migrators should not concern themselves with committing the work on the connection. The MigratorRunner will commit the connection work after running each Migrator.
