2 Storage Center 5.5 System Upgrade
Introduction
If configured to do so, Storage Center automatically checks for updates. However, once an
update is downloaded to your system, you must manually install the upgrade. For more
information about configuring the Storage Center upgrade process, refer to the Storage
Center 5.5 User Guide.
You cannot upgrade directly to Storage Center 5.5 from versions prior to Storage Center
4.5.6. You must first upgrade to Storage Center 4.5.6 and then install the Upgrade Package
that manages system updates.
To upgrade to Storage Center version 4.5.6, refer to the Storage Center 4.5 System
Upgrade.
Note You must upgrade the Storage Center software before making hardware changes to
a system.
