How to migrate from a file in Yii2, taking into account the use of vagrant?

Question

MySQL

I'm using Yii2 basic template out of the box. I run vagrant, run the migrations, everything works and does not give any errors. Regular migrations work fine. But file migrations don't make any changes to the database. I implement it like this:

public $maxSqlOutputLength = 300;
    public function safeUp()
    {
        $this->execute(
            file_get_contents(
                __DIR__ . '/../backup.sql')
        );
    }

Please let me know what could be the problem or where to look for it.

what if you try step-by-step debugging: I suggest inserting one simple UPDATE or INSERT command into the file and try to run the migration
