Migrating CiviCrm to WordPress CMS from Drupal
Export a csv list from Drupal or phpmyadmin? Then import it into WordPress via a plugin like https://wordpress.org/plugins/import-users-from-csv/ You can disable/delete the plugin after you are done. You will also want to use the plugin https://wordpress.org/plugins/civicrm-wp-member-sync/ to create/sync the users in Civi.
