How to use

create a folder in your working directory for the migrations.

mkdir migrations

Create a file called CURRENT_VERSION in this folder and insert the current version number

touch migrations/CURRENT_VERSION
echo '0' > migrations/CURRENT_VERSION

Include the DataMigration into your project.

add_action('init', function () {
   new DataMigration(get_template_directory() . '/migrations/');
});

In the migrations folder, create a migration file. These files should be constructed with the version number and the classname. ${VERSION}-${ClassName}.php

touch migrations/1-DoThisAndThat.php

The file should look like this

<?php

namespace Madebit\WordpressDataMigration;

class DoThisAndThat extends \Madebit\WordpressDataMigration\AbstractMigration {

    public function up()
    {
      // migrate data when migrating up
    }

    public function down()
    {
      // migrate data when migrating down
    }
}
?>

To migrate, visit the Rest endpoint << YOUR INSTALL >>/wp-json/m8b/v1/migrate. To test or execute a specific version add the ?version=<INT> parameter.
