title: Redirect old permalinks (page_id=x) wordpress
body: <p>I used to have my permalinks to standard format, something like <a href="http://example.com/?page_id=2" rel="nofollow noreferrer">http://example.com/?page_id=2</a>. Now I have changed this, using ISAPI rewrite in a httpd.ini file in the wp root folder. This is working, but I need to have the old page_id=x style pages redirect to the current permalinks which is in a form of <a href="http://example.com/subject" rel="nofollow noreferrer">http://example.com/subject</a>.</p>
  
  <p>I have looked at RedirectPermanent keywords etc, but nothing seems to really work. I have a very limited amount of pages, so a list where I specify all the page_ids is not really a problem. Anyone know how I can do this?</p>
