<p>Welcome to WordPress. Since you’re upgrading from b2 everything should be relatively
familiar to you. Here are some notes on upgrading:</p>
<ul>
<li>If you’re using an older version of b2, it's probably a good idea to upgrade
to at least .61 before making the leap to WordPress.</li>
<li>The templates are so much better, and there is so much more going on than
before it’s probably worth it to start from scratch and work back to your
design.</li>
<li>You need to transfer some of your settings from your old <code>b2config.php</code>
to <code>wp-config.php</code> file.</li>
<li>WordPress issues should be discussed in our <a href="http://wordpress.org/support/">support
forums</a>.</li>
<li><strong>Back up</strong> your database before you do anything. Yes, you.</li>
</ul>
<p>Have you looked at the <a href="../readme.html">readme</a>? If
you’re all ready, <a href="import-b2.php?step=1">let’s go</a>!</p>
