http://xenforo.com/community/threads/redirection-scripts-for-vbulletin-3-x.5030/ If you have imported your vBulletin 3.x database into XenForo, you can automatically redirect all traffic destined for your vBulletin content to its new location within XenForo. All you need to do is unzip these files and place them in the directory within which the vBulletin files with the corresponding names would be located. Any requests for the old URLs will be redirected with a 301 permanent redirection header.
