```
All migrations requires on `up` and one `down` method.
Example of a typical migration:
```js
/* eslint camelcase: "off" */
'use strict';
exports.up = function (db, cb) {
db.createTable('examples', {
id: { type: 'int', primaryKey: true, notNull: true },
created_at: { type: 'timestamp', defaultValue: 'now()' },
}, cb);
};
exports.down = function (db, cb) {
return db.dropTable('examples', cb);
};
```
