<div><p>Before you upgrade to a new release, you should have a current
backup copy of your server. </p>
<div class="section"> <p>You do not need to save your server when you have a current backup
copy that can be used to recover if a failure occurs. Be sure to keep this backup
copy until you save your entire server again. In the <span class="keyword">iSeries™ Information Center</span>,
the topic <a href="../rzaiu/rzaiuintro.htm">Back
up your server</a> contains information
on how to perform your save strategy and also the steps to automatically save
your entire server.</p>

procedure, determine the optical or tape device for the alternate IPL.</span></li>
<li class="stepexpand"><span>Save your server by using the alternate IPL device.</span> <p>Tapes
that are created with the Save System (SAVSYS) command cannot be used with
the automatic installation process. These tapes also do not provide a complete

next release, the upgrade process must be completed. If you do not complete
the upgrade and you want to return to the previous release of the operating
system, you need to initialize the disks and reload the server by using the
backup tapes that were created by the GO SAVE command (Option 21) just before
you began the upgrade.</div>
