title: Migrating Sequelize migrations
body: <p>I recently started working on a Sails project. It currently has migrations under migrations table with the following format.</p>
  
  <pre><code>20160826122004-create_users_table.js
  
  'use strict';
  
  module.exports = {
    up: function (queryInterface, DataTypes, done) {
      var users= queryInterface.createTable('users', {
        id: {
          type: DataTypes.INTEGER,
          primaryKey: true,
          autoIncrement: true
        },
        createdAt: {
          type: DataTypes.DATE
        },
        updatedAt: {
          type: DataTypes.DATE
        },
      })
      .then(function() {
        done();
      })
    },
  
    down: function (queryInterface, Sequelize) {
      queryInterface.dropTable('users');
    }
  };
  </code></pre>
  
  <p>However, there is no reference to those migrations in the codebase. Anyone knows how to run migrations since doing <code>sails lift</code> does nothing?</p>
