.htaccess Redirect Old Threads

Question

I have moved to mybb to vanilla and want to redirect old threads to the new format, so the indexed threads on Google aren't lost.

The old format is

showthread.php?tid=3003

Whereas the new format is

index.php?p=/discussion/3003

How would I redirect this via .htaccess?

Why is the new format index.php?p=/discussion/3003? Because /discussion/3003 is much nicer than index.php?p=/discussion/3003. — Adjam, May 12 '12 at 10:31
I agree, thats what the new software has, would i be able to change it to /discussion/3003 ? — h00j, May 12 '12 at 10:47
Yes. Ask it as a separate question though: How do I change index.php?p=/discussion/3003 to /discussion/3003 with .htaccess? — Adjam, May 12 '12 at 11:28

You will want to use a 301 redirect (permanently moved) so that google will update its indexes with the new URLS, as users are redirected.

RewriteEngine on
RewriteBase /
RewriteCond %{QUERY_STRING} tid=([0-9]*)$
RewriteRule showthread.php index.php?p=/discussion/%1 [L,R=301]

Also, for your follow up, yes, you would update the rule above to just redirect to the "clean" url, and then use a silent rewruite to ivoke index.php...corz.org/serv/tricks/htaccess2.php?page=2#not-so-simple – Eddie May 12 '12 at 12:17
For some reason with this rewrite it redirects to mysite.com/home/mysite/public_html/index.php?p=/discussion/3003 – h00j May 12 '12 at 13:04
add rewritebase / – Eddie May 12 '12 at 17:16
