I'm guessing there is a XML sitemap registered with google/bing/yahoo? Google respects the http redirection response(301), but only seems to maintain page rank for page to page mappings: <blockquote style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;" class="gmail_quote"> Don't do a single redirect directing all traffic from your old site to your new home page. This will avoid 404 errors, but it's not a good user experience. It's more work, but a page-to-page redirect will help preserve your site's ranking in Google while providing a consistent and transparent experience for your users. If there won't be a 1:1 match between pages on your old site and your new site (recommended), try to make sure that every page on your old site is at least redirected to a new page with similar content. </blockquote><a href="http://www.google.com/support/webmasters/bin/answer.py?answer=83105">http://www.google.com/support/webmasters/bin/answer.py?answer=83105</a> I know I'm statingthe obvious, but If you have access to your old web site access logs page referrer statistics, you can limit yourself to the pages that seem have high page rank, rather that trying to catch everything.
