Manages application migrations.

A migration means a set of persistent changes to the application environment that is shared among different developers. For example, in an application backed by a database, a migration may refer to a set of changes to the database, such as creating a new table, adding a new table column.

This command provides support for tracking the migration history, upgrading or downloading with migrations, and creating new migration skeletons.

The migration history is stored in a database table named as $migrationTable. The table will be automatically created the first time this command is executed, if it does not exist. You may also manually create it as follows:

CREATE TABLE migration (
    version varchar(180) PRIMARY KEY,
    apply_time integer
)

Below are some common usages of this command:

# creates a new migration named 'create_user_table'
yii migrate/create create_user_table

# applies ALL new migrations
yii migrate

# reverts the last applied migration
yii migrate/down

Since 2.0.10 you can use namespaced migrations. In order to enable this feature you should configure $migrationNamespaces property for the controller at application configuration:

return [
    'controllerMap' => [
        'migrate' => [
            'class' => 'yii\console\controllers\MigrateController',
            'migrationNamespaces' => [
                'app\migrations',
                'some\extension\migrations',
            ],
            //'migrationPath' => null, // allows to disable not namespaced migration completely
        ],
    ],
];
