Hello, I got a forum with 2 million posts. It was using a product called vbseo that changes the vbulletin default url to something more friendly.

Long story short, I need to revert back to those old url's. But so many people have linked to those seo friendly url's that if they or a bot follow those link, it will just get a 404 error.

Should I just create a new forum under a different url? That way I can keep the visitors that follow the links to friendly url? something like below?


And then on the old forum, have a big message at top, that says "New Forum URL Located Here" How do I tell google or other search engine bots to not crawl the old forum? Also I don't know how to mass do a 301 redirect...i could do manually...but 2 million is a lot.


My other problem is, that my new forum is using a SSO (single sign on) system that shares the "Community" sections like General talk, debates, chit chat, with about 4 other forums. So that means, if someone posts something under the chit chat section it gets shared with 4 other forums on 4 different domains.

If i put in a robot.txt file to not index or follow www.example.com/forum/display?=10 it won't follow or index any of the links that display on that URL? Cuz each community section has over 50,000 posts. 50,000x4 forums is definately gonna be duplicate content.

How do I go about this problem?

similar problem described here:
Problem with very large .htaccess [webmasterworld.com]

if it is an apache server, you might be able to do something with RewriteRule or RewriteMap directives.
