Seems like your current website lacks some functionality? Give it a spur by moving from WordPress to Drupal in a few mouse clicks. All you need to do is to provide both current and new website details, as well as choose what data you want to be transferred.
Automated WordPress to Drupal migration includes Free Demo, where some part of the content is moved to Drupal for free. Doing this way, you have a chance to preview the final result and make sure that Drupal is the very platform your website needs.
