+ * Migration is the base class for representing a MongoDB migration.
+ *
+ * Each child class of Migration represents an individual MongoDB migration which
+ * is identified by the child class name.
+ *
+ * Within each migration, the [[up()]] method should be overridden to contain the logic
+ * for "upgrading" the database; while the [[down()]] method for the "downgrading"
+ * logic.
+ *
+ * Migration provides a set of convenient methods for manipulating MongoDB data and schema.
+ * For example, the [[createIndex()]] method can be used to create a collection index.
+ * Compared with the same methods in [[Collection]], these methods will display extra
+ * information showing the method parameters and execution time, which may be useful when
+ * applying migrations.

+ * This is an analog of [[\yii\console\controllers|MigrateController]] for MongoDB.
+ *
+ * This command provides support for tracking the migration history, upgrading

+ * The migration history is stored in a MongoDB collection named

+ * this command is executed, if it does not exist.

+ * In order to enable this command you should adjust the configuration of your console application:

+ * ];
+ * ~~~

+ * Below are some common usages of this command:
+ *
+ * ~~~
+ * # creates a new migration named 'create_user_table'
+ * yii mongodb-migrate/create create_user_table
+ *
+ * # applies ALL new migrations
+ * yii mongodb-migrate
