This tutorial assumes you know how to install a self-hosted Wordpress site.  Let’s say you’ve got a wordpress powered blog that you’d like to transfer.  Here’s how to do it in just a couple quick steps:

1. Log into the dashboard of the old site and under “tools” click “export”.  Wordpress will export all of the posts, pages, comments and even images into an XML file.
2. Log into the dashboard of the new site and under “tools” click “import”.  Select that xml file that you saved in your last step and begin the import.  Voila! Your Wordpress site has now been duplicated on the new site.

Remember that this does not affect the theme or any customizations or plugins you were using.  Is that easy or what?
