Assuming the update_field() call in your post works as expected (I haven’t looked into this) you should be able to loop the output from WordPress’s get_post_meta() function.

Something like this:

function update_fields_for_id( $post_id ) {
	$fields = get_post_meta( $post_id );

	foreach ($fields as $field_name => $field_value) {
		// Don't process fields with leading underscore
		// which are marked as private for internal use only
		if ( 0 !== strpos( $field_name, '_' ) ) {
			update_field( $field_name, get_field( $field_name, $post_id ), $post_id );
		}
	}
}
