It does not really matter: You can also set up a new MW 1.21 install on the new server as Mark said. In Mark's first step, you should not only copy over your LocalSettings.php file and the folder images/, but also extensions/ (if you used any; don't forget that there might be newer versions to update to) and the folder skins/, if you had modified a skin or created your own skin.
