Looks like you might need :
2. Install the WP All Import Pro Plugin
To prepare for the migration, you’ll also have to take some steps on the WordPress side. Specifically, we recommend the WordPress plugin WP All Import Pro, with the advanced custom field (ACF) add-on. What the add-on does is allow us to map fields within Drupal to custom ACFs within WordPress.
After you download the WP All Import Pro plugin, you’ll then upload the XML, JSON, or CSV file you created when you mapped your Drupal data.
Then, decide the data you want to import. Since you are migrating your whole site, you’ll likely import all of your data. This process can include posts, pages, taxonomies, users, or custom post types added by other themes and plugins.
