Vbulletin to SMF 301 Permanent URL Redirects

Note: This is an archived post. Information may not be relevant now.

Switching to SMF from vbulletin is easy. The database converters are easily available. The only tricky part is to keep the old links alive, which isn’t difficult either with a little regex knowledge and Apache mod_rewrite power.

Since this is a permanent switch, 301 redirects are used to send acknowldgements to web spiders. The old vbulletin installation used SEO friendly URLs and the new SMF has PrettyURLs Mod, which i think despite of no SMF experience at all is a must.

The following is the content from .htaccess file which should reside at the root directory of your forum.


RewriteEngine on
RewriteBase /

#Redirect to
RewriteCond %{HTTP_HOST} ^$ [NC]
RewriteRule ^(.*)$$1 [R=301]
