// Transfer relationships to another item.
$oldUser->transferTo($newUser); // Returns the total rows changed.

// Bob's your uncle, now oldUser can be deleted.
$oldUser->delete();

// Return boolean if it would have any dangling relationships if deleted.
// The false param tells it not to throw an Exception
$newUser->checkDangling(false);
