It seems like you are having config.php file issues with parameters missing such as DB_PORT.
define('DB_PORT', '3306');
I imagine that will not be the last thing that you will be missing...
Take a look here for some helpful info:

Thanks for the quick response, but i am going from 2.0.1.1 to 2.1.0.1 and the links you sent were from 1.5 to 2.0. Is there a way to manually fix this or just upload a new config file?

The script (as noted) can move from any lesser database version to the current. It is the final destination you are looking for correct? If you follow the direction you will get a current config.php file (root & admin) that you can use for the v2.1.0.1 version database. My advise is not to take any shortcuts in the migration and not to use a live database.
