title: Sequilize/Umzug: where to store a state of a database schema?
body: <p>So, I want to write an application which use some data migration. Where should I store a current state of db?</p>
  
  <p>For example: I have a production server and my development machine. I wrote an application and 3 migrations for it. When I deploy the application server also runs 3 migrations.
  Now I'm going to write the 4th migration. How does server recognize that it need to run only 4th migration and it already run previous 3 migrations?</p>
