<div class="BodyAfterHead"><a name="1104695">RAID level migration is the process of converting one RAID configuration to </a>another. When you migrate a unit to a different configuration, the user data on it is redistributed to the format of the new configuration. This data redistribution process is a background task, similar to the rebuild or verify processes.</div>
<div class="Body"><a href="#1208715" name="1104696">Figure: Show RAID Level Migration Example</a> shows an example of how data is reconfigured during a migration. In this example, the migration is from a 3-drive RAID 0 to a 4-drive RAID 5, with both having the same stripe size. As can be seen, every piece of user data is moved from its original physical location.</div>
