Exporting member info incl. passwords

With WordPress your content is separate from your presentation so there is no need to worry about this is you are simply changing to a new theme or design.

You can export your members to a csv file, but this does not include their usernames and passwords. You can look in the WordPress Codex for more information about how to work with the WP database.
