<h1 class="topictitle1">Scenarios: Data migration</h1>
<div><p>Review a number of data migration examples and find information
about performing these types of data migrations.</p>
<p>This topic contains a number of data migration scenarios. Use these scenarios
to help you become familiar with the details involved with migrating your
data to another server.</p>
<dl><dt class="dlterm">Data migration scenario 1: Migrating from V5R1 on a 620 to V5R4 on an
520 server</dt>
<dd>In this scenario, you have a 620 server, you are running V5R1, and you
want to migrate your data to a 520 server.</dd>
<dt class="dlterm">What to do:</dt>
<dd>You cannot install <span class="keyword">i5/OS™</span> V5R4
on your 620 server. To migrate your data, you will save the data to a tape
drive that is compatible with the 520 and then restore the data on the 520.
To perform this data migration, first prepare for the migration, then complete
the migration.</dd>
<dt class="dlterm">Data migration scenario 2: Migrating from V5R1 on a 740 to V5R4 on a partitioned
570 server</dt>
<dd>In this scenario, you have a 740 server, you are running V5R1, and you
want to migrate your data to a partitioned 570 server.</dd>
<dt class="dlterm">What to do:</dt>
<dd>You can install <span class="keyword">i5/OS</span> V5R4
on your 740 server. To migrate your data, you will first install V5R4 on your
740 server, then save the data to a tape drive that is compatible with the
partitioned 570 and restore the data on the 570. To perform this data migration,
first prepare for the migration, then complete the migration.</dd>
<dt class="dlterm">Data migration scenario 3: Migrating from V5R1 on a partitioned 830 server
to V5R4 on an 825 server</dt>
<dd>In this scenario, you have an 830 server with multiple V5R1 partitions,
and you want to migrate your data to an 825 server.</dd>
<dt class="dlterm">What to do:</dt>
<dd>You can install <span class="keyword">i5/OS</span> V5R4
on your 825 server. To migrate your data, you will first install V5R4 on all
partitions of your 830 server, then save the data from each partition to a
tape drive that is compatible with the 825 and restore the data on the 825.
To perform this data migration, first prepare for the migration, then complete
the migration.</dd>
<dt class="dlterm">Data migration scenario 4: Installing a new version of <span class="keyword">i5/OS</span> on
your server</dt>
<dd>In this scenario, you are running V4R5, V5R1, V5R2, or V5R3 on your server
and you want to upgrade to V5R4.</dd>
<dt class="dlterm">What to do:</dt>
<dd>If you are installing a new version of <span class="keyword">i5/OS</span> on
the same server, it is not necessary to perform an explicit data migration.
You can use the Install the <span class="keyword">i5/OS</span> release
topic to install V5R4 on your server.</dd>
<dt class="dlterm">Data migration scenario 5: Upgrading your server to an 890 server</dt>
<dd>In this scenario, you want to upgrade to the new 890 server.</dd>
<dt class="dlterm">What to do:</dt>
<dd>If you are upgrading to a new iSeries™ server without changing the serial
number, it is not necessary to perform an explicit data migration. You can
use the Upgrades topic.</dd>
<dt class="dlterm">Data migration scenario 6: Migrating data from one partition to another</dt>
<dd>In this scenario, you want to migrate data from one partition to another
on your server.</dd>
<dt class="dlterm">What to do:</dt>
<dd>If you are migrating data from one iSeries server partition to another partition
on the same server, follow the instructions for Restoring a Logical Partition
to Another Logical Partition--Checklist 22 in Chapter 3 of Backup and Recovery
Guide.</dd>
