PHPBB to Vanilla

So I'm going to be converting my board sometime in the future, and there's something I'm worried about.

The current board has a lot of tutorials that are linked to by other sites/blog which bring in a lot of traffic. How can I preserve the url? or even redirect the old url to the new url permanently?

You could use htaccess to perform redirects/masks to the new urls?

Care to explain? or point me in the right direction to do that?

Congratulations on the move to vanilla
Its a pleasure to code for/with.

That is for a permanent redirect (which is what you will want). Obviously for the code above you will have to redirect every tutorial individually. I don't know if there is a way to do this dynamically from phpbb urls to vanilla ones.

Thanks!
