prerequisite tasks:</p>
<ul><li>Obtain and review the preventive service planning (PSP) information. <p>The
PSP document for V5R4 upgrades is SF98168. Review this document for the most
current information about conditions that can affect your upgrade.</p>
</li>
<li>Review the Memo to Users. <p>This document provides information about
software and hardware changes that can potentially affect your system operations.</p>
</li>
<li>View the Migration Web site. <p>This Web site includes information about
the current migration and upgrade paths, a link to relevant Redbooks™,
and information about converting from SPD to PCI-attached I/O.</p>
</li>
<li>Review the <cite>Performance Capabilities Reference</cite> available on
the Performance Management Web site. <p>This reference provides information
about server performance that is useful for customers who plan to upgrade
their servers and software.</p>
</li>
<li>Plan the upgrade.</li>
