Duplicator works almost perfectly in transferring from one site to another, including (as we now know) locally hosted servers such as WAMP and XAMPP. Almost.
The only thing that seems to fail is the linking to avatar images. I tried it with the most popular avatar plugins that allow for adding local (private) avatars, such as Simple Local Avatars, Add Local Avatar and User Avatar, meant for users who don't use Gravatar. In all cases, regardless of the site being hosted online or a local server, avatars that were showing up properly on the original site default to the Gravatar mystery man even though the image is available on site.
