Moving from IPB to vBulletin - having some SEO "Friendly URL" issues

Ok, I'm not sure if this is the correct place to post this question, so my apologies in advance if it's not in the right place. I am in the process of moving from IPB software using "Kim's FURL SEO URLs" mod to vBulletin. I was able to use the 404 script in ImpEx to redirect the non-SEO'd URLs from IPB to my new vbulletin installation, but I can't figure out how to reverse what the FURL hack is doing. Can anyone take a look at my htaccess and tell me how to reverse it? So basically I want to do this:

Friendly URL --> IPB Standard URL (index.php?...) --> vBulletin URLs

In the next week or so I'm going to add vBSEO (use it on one of my other sites and love it), but I want to conquer this step first:

Code:

it's not going to happen.

if you ever deleted 1 post, 1 member, or 1 thread, the new vb id's won't match the old ipb id's. there's no real way to redirect it.

Ok, I'm sorry, I should have been more clear in my post.

I'm already successfully redirecting all of my IPB posts/threads to the new vbulletin threads using the Impex 404.php script which uses the importids to match the IPB thread # to the VB thread #. That part of the project is done.

Now I just need to reverse one the Friendly URLs that I had setup on IPB. Basically I just need to know how to swap this code:

Code:

# DO THE TOPIC URLS
RewriteRule ^(.*)-t([0-9][0-9]*)-s([0-9][0-9]*)\.html(.*)$ index.php?showtopic=$2&st=$3

I tried just flipping it around but I think my syntax is wrong:

Code:

# DO THE TOPIC URLS
RewriteRule ^index.php?showtopic=$2&st=$3 (.*)-t([0-9][0-9]*)-s([0-9][0-9]*)\.html(.*)$

What is an example URL that you want to redirect (and what is corresponding target URL)?

I'm not an expert on this, but i think $2 and $3 var's aren't set yet, and that's the problem.

I think you need to do something like

Code:

RewriteRule ^index.php?showtopic=([0-9][0-9]*)&st=([0-9][0-9]*)\.html(.*) (.*)-t$2-s$3$

i doubt that works, but that's the general idea on it.

Hi everyone - thank you for the responses so far, they have been very helpful. I'm actually now facing another problem: I had my old IPB forum under the root directory, but I now have the vbulletin forum under /forums. No big deal there. The problem comes in now that I have Drupal installed in the root directory. As soon as I installed Drupal, all of my re-directs from my old threads to my new threads stopped working because Drupal uses the same index.php program file name. So now if you go to one of my old threads under IPB at domain.com/index.php?showtopic=29738 it just shows the default Drupal home page like you were visiting domain.com/index.php. I think this is killing me in Google because all of these similar URLs are showing up in a site:domain.com search way before the new vbulletin urls.

Here is the code for Drupal's friendly pages. Is there a way to do it so that the "index.php?showtopic=123456" pages redirect to the new forums?

Code:

  # Rewrite current-style URLs of the form 'index.php?q=x'.
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

Make sure that your Drupal rewrite rules are inserted AFTER redirect rules in .htaccess.
