rename wp-config-sample.php, wp-config.php

I am about to upload my wordpress blog site to the remote host and I need to rename wp-config-sample.php as wp-config.php. But my version of wordpress has both the wp-config-sample.php and the wp-config.php. I understand some of the dowloaded versions of wordpress don’t have wp-config.php. They only have wp-config-sample.php. If I rename wp-config-sample.php as wp-config.php, the server tells me the file already exists.
Can I delete wp-config-sample.php? Because I can see that wp-config.php contains all the necessary information and wp-config-sample.php has a little information which is also contained in wp-config.php.
Thanks
