<h2 id="rzahymigration">Migration considerations</h2>
<p>Directory Server is automatically installed when you install i5/OS. The
first time the server is started, it automatically migrates any existing configuration
and data. This can cause a long delay before the server is started the first
time.</p>

<div class="notetitle" id="wq80">Note:</div>
<div class="notebody">Migration of the configuration and schema files is done
during install and the first server startup. Once this first server startup
is completed, if the configuration and schema files in /qibm/userdata/os400/dirsrv
are restored from a backup of a previous release, the schema and configuration
for the new release will be overlaid with the previous release's files which
will not be migrated again. Restoring a previous release's schema and configuration
after migration has occurred may cause your server not to start as well as
other unpredictable errors. If a backup of the server configuration and schema
are desired, this data should be saved after the server has been successfully
started.</div>
<p>If you have a Directory Server running under V5R3 or V5R21, see <a href="rzahymig-po.htm#rzahymig-po">Migrate to V5R4 from V5R3 or V5R2</a>.</p>
<p>If you have a Directory Server running under V4R4, V4R5, or V5R1, you can
migrate your data to V5R4. For more information, see <a href="rzahymi4-po.htm#rzahymi4-po">Migrate data from V4R4 ,V4R5, or V5R1 to V5R4</a>.</p>
<p>If you have a network of replicating servers, see <a href="rzahyrepmig.htm#rzahyrepmig">Migrating a network of replicating servers</a> for
more information.</p>
<p>If you are using Kerberos, see <a href="rzahykerberosmig.htm#rzahykerberosmig">Kerberos service name change</a>.</p>
