I got very close, playing around with converting it on my own. I took the .htaccess file that was generated on the old server and used it to create this (placed in my lighttpd config file):
url.rewrite-once = (
"^/forum/([^/]+)/page/([0-9]+)/?$" => "/forum.php?id=$1&page=$2",
"^/forum/([^/]+)/?$" => "/forum.php?id=$1",
"^/topic/([^/]+)/page/([0-9]+)/?$" => "/topic.php?id=$1&page=$2",
"^/topic/([^/]+)/?$" => "/topic.php?id=$1",
"^/tags/([^/]+)/page/([0-9]+)/?$" => "/tags.php?tag=$1&page=$2",
"^/tags/([^/]+)/?$" => "/tags.php?tag=$1",
"^/tags/?$" => "/tags.php",
"^/profile/([^/]+)/page/([0-9]+)/?$" => "/profile.php?id=$1&page=$2",
"^/profile/([^/]+)/([^/]+)/?$" => "/profile.php?id=$1&tab=$2",
"^/profile/([^/]+)/([^/]+)/page/([0-9]+)/?$" => "/profile.php?id=$1&tab=$2&page=$3",
"^/profile/([^/]+)/([^/]+)/favorites/?$" => "/profile.php?id=$1&tab=favorites",
"^/profile/([^/]+)/?$" => "/profile.php?id=$1",
"^/view/([^/]+)/page/([0-9]+)/?$" => "/view.php?view=$1&page=$2",
"^/view/([^/]+)/?$" => "/view.php?view=$1",
"^/rss/?$" => "/rss.php",
"^/rss/forum/([^/]+)/?$" => "/rss.php?forum=$1",
"^/rss/topic/([^/]+)/?$" => "/rss.php?topic=$1",
"^/rss/tags/([^/]+)/?$" => "/rss.php?tag=$1",
"^/rss/profile/([^/]+)/?$" => "/rss.php?profile=$1"
)
Most of the functionality works, but it still seems to be breaking on some minor things (like adding a topic to your favorites while logged in).
I hadn’t bothered to go back and see if those minor things were working correctly on the old server.
