Stack Overflow sites all have pretty urls which include the question title. In the HTML it also have canonical url for that page.
I just found out that when I change the question title, the url is changed immediately. The canonical url is also updated. Does it mean that as long as the page with the old canonical url redirects to the new canonical url, then search engines will update their records of the canonical url as well?
Is there anything else that one can actively do to make the url change even more smoother?
