185<h2>Upgrade FeedWordPress</h2>
186
187<p>It appears that you have installed FeedWordPress
188<?php echo FEEDWORDPRESS_VERSION; ?> as an upgrade to an existing installation of
189FeedWordPress. That's no problem, but you will need to take a minute out first
190to upgrade your database: some necessary changes in how the software keeps
191track of posts and feeds will cause problems such as duplicate posts and broken
192templates if we were to continue without the upgrade.</p>
193
194<p>Note that most of FeedWordPress's functionality is temporarily disabled
195until we have successfully completed the upgrade. Everything should begin
196working as normal again once the upgrade is complete. There's extraordinarily
197little chance of any damage as the result of the upgrade, but if you're paranoid
198like me you may want to back up your database before you proceed.</p>
199
200<p>This may take several minutes for a large installation.</p>
