For those of you who don’t know, MT stands for Movable Type and is SixApart‘s blogsystem. It’s a pretty simple plain-text format which many blogsystems (like for instance EE) can do an import from. I used the format description found here.
Download the script here: Serendipity (s9y) MT Export
The process is simple — just edit the following lines in the script:
$db_host = "localhost";
$db_user = "db_user";
$db_pass = "db_password";
$db_name = "db_name";
$filename = "s9y_export_mt.txt"; // file to write to
Upload the script and load it in your browser. A file (s9y_export_mt.txt by default) will be written. This is the file you import.
Enjoy, and ask in the comment section if something is unclear :-)
