Moving an entire wordpress site from one domain to a new domain and database

First add

define('WP_SITEURL', 'http://example.com');
define('WP_HOME', 'http://example.com');

To your wp-config.php file (obviously change example.com to your domain)

then login and once you see the admin panel navigate to http://yoursite/wp-admin/options.php

there you can change home and siteurl to your new domain and save.

You will also need to change the links for images and other media in your post database table.
