Howdy! We’re about to begin the process to import all of your Movable Type entries into WordPress. Before we get started, you need to edit this file (import-mt.php) and change one line so we know where to find your MT export file. To make this easy put the import file into the wp-admin directory. Look for the line that says:
define('MTEXPORT', '');
and change it to
define('MTEXPORT', 'import.txt');
You have to do this manually for security reasons.
If you've done that and you’re all ready, let's go! Remember that the import process may take a minute or so if you have a large number of entries and comments. Think of all the rebuilding time you'll be saving once it's done. :)
On our test system, importing a blog of 1189 entries and about a thousand comments took 18 seconds.
The importer is smart enough not to import duplicates, so you can run this multiple times without worry if—for whatever reason—it doesn't finish.
