<p>Howdy! We&#8217;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 (<code>import-mt.php</code>) and change one line so we know where to find your MT export file. To make this easy put the import file into the <code>wp-admin</code> directory. Look for the line that says:</p>
<p><code>define('MTEXPORT', '');</code></p>
<p>and change it to</p>
<p><code>define('MTEXPORT', 'import.txt');</code></p>
<p>You have to do this manually for security reasons.</p>
<p>If you've done that and you&#8217;re all ready, <a href="import-mt.php?step=1">let's go</a>! 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. :)</p>
<p>On our test system, importing a blog of 1189 entries and about a thousand comments took 18 seconds. </p>
<p>The importer is smart enough not to import duplicates, so you can run this multiple times without worry if&#8212;for whatever reason&#8212;it doesn't finish. </p>
