Transferring your WordPress application includes copying your files and database and modifying the wp-config.php file in your main WordPress folder.
In wp-config.php you should change the MySQL settings:
DB_NAME – here you should enter the name of the WordPress database, e.g. :
DB_USER – here you should enter the username with privileges to access the blog database, e.g. :
DB_PASSWORD – the password for accessing the database:
DB_HOST – the MySQL host; in most cases you won’t have to change this:
In case you wish to use the transferred application with another domain, or in another folder, you should also change the siteurl and home options in your WordPress database. You can do this using the phpMyAdmin tool available in your cPanel.
Once in phpMyAdmin, select your WordPress database and browse the table wp_options. Find the options siteurl and home and change their values to the desired URL.
