    Flyway.configure()
          .dataSource(dataSource)
          .locations("db/migration/ds2")
          .load()
          .migrate();
    return builder
        .dataSource(dataSource)
        .packages(Role.class)
        .properties(jpaProperties2().getProperties())
        .persistenceUnit("domain2")
        .build();
}

I disabled spring.flyway.enabled for that.
