The updated name will immediately appear in the Close UI and only valid values for the updated `type` will be returned by the Contact API.


        Some of the type changes need to convert all of the existing values for a given Custom Field to the new type. When this is required, the response will include an additional `converting_to_type` field. When the conversion is done, `converting_to_type` will no longer be returned.'
