1: use the search function, this has been ask and solved a million times
2: create an admin dir under controllers
3: copy your controllers there
4: setup routing in routes.php

example:
$route['admin'] = 'admin/default_admin_controller';
$route['admin/system'] = 'system';
$route['admin/system/(.+)'] = 'system/$1';
