Hi Jan
No, that is one of the 'bugs' of DW8 that changed with DW9 because of the brand new way of managing URLs.
You should not need to do anything. Only if you have links hardcoded to the friendly url instead of the Default.aspx?id=123 version of it.
If the page is very important for your SEO or you have external links into the page, you should consider creating a Direct path in MC making a 301 from the old to the new. Most pages will be re-indexed on the new URL within a couple of days.
