I have a NewsRepository and a News model.
The storagePid is 74.
I have a script which checks if the endtime field of the new record is overdue. If it is, I want to move the record in another folder (UID 170).

When I do:

```
$news = $newsRepository->findByUid( 1 );
$news->setTitle( 'News ' . rand(1,99999) );
$news->setPid( 170 );
$newsRepository->update( $news );

```

The title is changed, but the PID is not.

So, how can I move the new onto another page?
