Upgrade paths
In an upgrade, the target server retains the same serial number as the source server. Before you upgrade your server, consider this information regarding valid upgrade paths.
If you cannot upgrade your server to an 8xx model, you can migrate the data from your server to a new model. For information about migrating your data to a new server, see Migration.
You can upgrade the capacity of select servers without upgrading to a new server by activating one or more standby processors on that server. In fact, before you can upgrade your server, all of the processors on that server must be activated. For more information, see the Capacity on Demand topic.
For more information about valid upgrade paths, contact your marketing representative or business partner, or click the Upgrade link on the IBM® FACT Web site.
