<h1 class="topictitle1">Upgrade considerations</h1>
<div><p>This topic contains information about upgrading iSeries™ Access
for Web from a previous release.</p>
<div class="section"><h4 class="sectiontitle">Upgrade process</h4></div>
<div class="section">Upgrading iSeries Access for Web from a previous release is
performed in two steps. <ol><li>Install the new release of iSeries Access for Web on the iSeries server.
This overlays the previous release of the product.</li>
<li>Configure, or reconfigure, iSeries Access for Web. This enables
the new functions provided in the new release and preserves all of the existing
user-generated data.</li>
</ol>
</div>
<div class="section"><h4 class="sectiontitle">Portal environment considerations</h4>If the iSeries Access
for Web default pages were created during the original portal configuration
and you changed those pages, it is recommended that you do not re-create the
default pages when you upgrade. If you re-create the pages, all customizations
and configurations settings are lost. <p>The page creation option is a parameter
on the iSeries Access
for Web configuration command CFGACCWEB2. Specify WPDFTPAG(*NOCREATE) if
you do not want to re-create the default pages. Specify WPDFTPAG(*CREATE)
to create the default pages. Refer to the help text for the CFGACCWEB2 command
and its parameters for more detail.</p>
<div class="note"><span class="notetitle">Note:</span> If you used the IBM<sup>®</sup> Web Administration
for iSeries wizard
interface to create the portal instance and deploy the iSeries Access for Web portlets, the iSeries Access
for Web default pages were created automatically. </div>
</div>
<div class="section"><h4 class="sectiontitle">Upgrade from V5R1 iSeries Access for Web</h4>If you
have V5R1 iSeries Access
for Web (5722-XH1) installed on your server, installing V5R4 iSeries Access
for Web (5722-XH2) has no impact on the V5R1 installation. V5R1 and V5R4 iSeries Access
for Web can coexist on the same server. <div class="p">When V5R4 iSeries Access for Web is configured
using the CFGACCWEB2 command, the following automatically occur the first
time the command is run: <ul><li>V5R1 iSeries Access
for Web user generated data is copied to the V5R4 iSeries Access for Web directory structure.</li>
<li>The V5R1 iSeries Access
for Web policy information is copied to the V5R4 iSeries Access for Web configuration. </li>
<li>The V5R1 iSeries Access
for Web file content-type (MIME-type) mappings are copied to the V5R4 iSeries Access
for Web configuration.</li>
</ul>
To prevent these from happening automatically, follow these steps before
running the CFGACCWEB2 command: <ol><li>Create the file /QIBM/UserData/Access/Web2/config/migration.properties. </li>
<li>Using an editor, add was35migrationrun=true to the migration.properties
file.</li>
</ol>
