Possible Duplicate:How to tell google that i have changed my website urls? I don;t know how to ask the question but situation is this. I have the old site with a lot of content that has recently been improved, built with another technology, among other things all the URL's have been coded in a nicer way.Old site:example.com/1/4444/p23a.phpNew site:example.com/music/rockThe problem is that Google and other search engines already cached a lot of this content and is appearing pretty high up. If I just redeploy the site with new links, I'm afraid all the search results will be invalid. Is there a way to solve this? All pages are dynamic, so I can't go and do any batch renaming or inserting redirect code. Also, I would eventually like for the old links to phase out, but not that people get broken links in Google search.
Old content, new URL's, how to keep the old URL's still working? 301 redirects?
