How to import users from oxwall to buddypress


I need to import all data (users, avatars, passwords, forums, topics, replies) from oxwall (social networking software) to buddypress.

bbPress 2.1 includes a conversion tool to import forums/topics/replies/users from some of the popular forum packages eg. bbPress or phpBB.

There is an ‘example’ file also included as a ‘reference template’ that if my forum software is using a SQL database then I could modify this to be a custom importer by matching the correct database tables/fields etc.

The file is called ‘example.php’ and is located in /wp-content/plugins/bbpress/bbp-admin/converters.

The thing is - I have no idea how to do that...

Any help will be appreciated
