Change list and field properties - including lookup column reassosiation (cross site).
I have removed some list types and some column types, but be careful using this tool, as you may break your list if you alter the wrong fields.

If a property is neither "Yes" nor "No" for the current field, it has a default value and does not have to be set unless you want to change the fields behavior
