I had a client with 21 pages including images on their WP site. To avoid risks to their live site I set up a sub-domain with a new database and WP site. Exported and imported XML to new WP Site. Installed Joomla connected to the new database on subdomain. Installed CMigrator and it worked. Don't be alarmed when this is no content displayed on your site. Go to Administration/Content and its all there. Just needs some formatting and linked to a menu.
