Transferring your ZenCart application includes copying your files and database and modifying the two configure.php files in includes/ and admin/includes/ folders to work with the new server settings.
The most important settings which should be modified in includes/configure.php are:
HTTP_SERVER - you should set this to your domain name, e.g. http://yourdomain.com:
define('HTTP_SERVER', 'http://yourdomain.com');
DIR_WS_CATALOG - the relative path to your shop:
define('DIR_WS_CATALOG', '/shop/');
DIR_FS_CATALOG - the absolute path to your shop, e.g. /home/user/public_html/shop/:
define('DIR_FS_CATALOG', '/home/user/public_html/shop');
DB_SERVER - you should set this to localhost:
define('DB_SERVER', 'localhost');
DB_SERVER_USERNAME - the username with privileges to access the shop database:
define('DB_SERVER_USERNAME', 'user_zc1');
DB_SERVER_PASSWORD - the password for accessing the database:
define('DB_SERVER_PASSWORD', 'zcpassword');
DB_DATABASE - the shop database:
define('DB_DATABASE', 'user_zc1');
In admin/includes/configure.php, along with the settings above, you should also modify:
DIR_WS_ADMIN - the relative path to the admin folder:
define('DIR_WS_ADMIN', '/shop/admin/');
DIR_FS_ADMIN - the absolute path to the admin folder, e.g. /home/user/public_html/shop/admin/:
define('DIR_FS_ADMIN', '/home/user/public_html/shop/admin/');
