After following the steps outlined here to import the old MovableType content, I created the following mod_rewrite rules to redirect requests for old content to the new archive copy of the site:
RewriteEngine On
RewriteBase /
# Redirects individual posts:
RewriteCond %{REQUEST_URI} ^/weblog/archives/[0-9]{6}\.html.*$
RewriteRule ^weblog/archives/([0-9]+)\.html.*$ http://archive.tylerdave.com/$1/ [R=301,L]
# Redirects monthly archives:
RewriteCond %{REQUEST_URI} ^/weblog/archives/20[0-9]{2}\_[0-9]{2}\.html.*$
RewriteRule ^weblog/archives/20([0-9]{2})\_([0-9]{2})\.html.*$ http://archive.tylerdave.com/date/20$1/$2/ [R=301,L]
# Redirects individual posts:
RewriteCond %{QUERY_STRING} ^entry_id=([0-9]{1})$
RewriteRule ^mt/mt-comments\.cgi http://archive.tylerdave.com/00000%1/? [R=301,L]
# Redirects old comments URLs to the posts:
RewriteCond %{QUERY_STRING} ^entry_id=([0-9]{2})$
RewriteRule ^mt/mt-comments\.cgi http://archive.tylerdave.com/0000%1/? [R=301,L]
RewriteCond %{QUERY_STRING} ^entry_id=([0-9]{3})$
RewriteRule ^mt/mt-comments\.cgi http://archive.tylerdave.com/000%1/? [R=301,L]
# Redirects other requests to me-comments.cgi to the archive's home page:
RewriteCond %{REQUEST_URI} ^/mt/mt-comments\.cgi.*$
RewriteRule . http://archive.tylerdave.com/ [R=301,L]
# Redirects the index page::
RewriteCond %{REQUEST_URI} ^/weblog/archives/index.html$
RewriteRule . http://archive.tylerdave.com/ [R=301,L]
# Redirects RDF feed:
RewriteCond %{REQUEST_URI} ^.*index.rdf$
RewriteRule . http://archive.tylerdave.com/feed/rdf/
These rules account for more than 95% of the traffic to the old site. I will continue to monitor the logs and update the rules as necessary.
