Migrate database

To migrate the database, you need to add migrate command.

The Mysql backup has another great feature: migrating your database from a source database to a target.

As you know, to restore a database from a source to a target database, you need 2 operations: which is to start by backing up the source database and then restoring the source backed database to the target database. Instead of proceeding like that, you can use the integrated feature (migrate), which will help you migrate your database by doing only one operation.

The migrate operation is irreversible, please backup your target database before this action.
