how can i make google cache delete old webpages and start to index new ones

My question is about the old content which is already indexed in google by the old URL but whenever anyone search on google for any of my old content

the results is with the old URLS

Example of real time situation

when any one search for [OLD NEWS] Octopus Paul fortune-teller gets a copy of the World Cup or German Muller wins the Golden Boot awards and the best young player or Spain crowned champion after the World Cup victory over the Netherlands

i find results like http://www.domain-name.com/Sectionnewsdetail.aspx?id=10132 which is deleted and land on page not found

So I created a webpage with the old name Sectionnewsdetail.aspx to redirect to the new content page -- http://www.domain-name.com/Content/SectionNews.aspx?NewsID=13855

so that the user will not go to a page not found

but my question Now is

will what i have done help to delete the last cached URL from google and start to index new URLs as URLs in google search will go to my new URL afer redirecting the URL cached in google to my new URL

OR

what i have done make google knoow that the Old URLs are still alive as i created dummy page with the old name to redirect to the appropiate URL and i must keep the the page not found which may make google know that these URL are dead now

 

this is nearly impossible to do . I had the same problem for quite some time and searched on the Internet for this omission but was unable to find one . The best thing that you can do is to constantly update the webpage with the new content and in the course of time automatically Google will update its cache

 

If you regular change or update your content then it is best that you also regularly change or update your sitemaps as well and submit them to Google. Also to get your changes recognized and to prevent Google from showing the old URLs instead of the new ones you should also highlight your page and build links to such pages.

 

It's not seems possible that uyou can manually change, only google crawler can make change.

 

You can block pages from google you dont use anymore ( robots.txt ) and submit new sitemaps to let google know of changes. Make new links as has been posted previously . Im at the same position at the moment . But it seems like long term process .

 

I don't think it's possible to do this at this point..

 

Its not easy but possible. need to remove old url from Google webmaster and recreate sitemap and upload.
