automatic upgrade. That means that, if you have OpenACS 4.5 or
better, you should always be able to upgrade all of your core
packages automatically. If you haven't changed anything, no
manual intervention should be required. If you are running OpenACS
prior to 4.5, upgrading will require manual effort.</p><p>If all of these conditions are true:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc;">

</ul></div><p>then you can upgrade automatically using the automated installer
in the OpenACS Package Manager (APM), and you can probably skip the
rest of this chapter. To upgrade directly from the OpenACS
repository using the APM:</p><div class="orderedlist"><ol class="orderedlist" type="1">

Repository" and select the packages to install or upgrade.</p></li><li class="listitem"><p>The APM will download the requested packages from OpenACS.org,
install the files on your hard drive, run any appropriate database
upgrade scripts, and prompt you to restart the server. After
restarting the server again, the upgrade is complete.</p></li>
