You can't change the key of a hash because the key decides how to find the data based on an algorithm.

You must instead move the value, easiest done this way: 

$hash{newkey} = delete $hash{oldkey};

The delete removes the value from the old hash location and returns the value, allowing you to put it in the new hash location.
