wordpress_migrate supports migrating WordPress blog exports (WXR format) into Drupal using the Migrate module. Import of posts, pages, comments, attachments, tags and categories is supported. Imports can be rolled back completely.
The main theme for version 2.3 was- this involved a complete redesign of the UI, changing it to a step-by-step wizard process and enabling more flexibility (e.g., separate options like attachment fields for blog posts and pages). If you have an existing WordPress migration set up but are not yet committed to the results (i.e., you're still testing it), it is recommended to roll back and remove the settings, and reconfigure from scratch through the new wizard.
