Forum migration from WordPress to Drupal

X-notifier forum system has been changed from WordPress to Drupal.
Old forum was based on WordPress+bbPress.
I chose WordPress because it is very popular content management system.
But it did not meet my expectation.
I wanted to import all the post and user information from the old forum.
Unfortunately, I couldn't find a way to do it.

I am sorry for your inconvenience.
Please register to new forum.
It is highly recommended to use the same username and password from the old forum for new forum.
