Upgrade considerations

Learn about the considerations you need to keep in mind before you upgrade your controllers.

Upgrading to newer models

If you are replacing the controllers to upgrade to a new model, keep in mind that your current storage array might have premium features installed that the new model cannot support. For example, E2700 controllers do not support the legacy Snapshots premium feature.

If you replace E2600 controllers with E2700 controllers, and your storage array was using the legacy Snapshots feature, you must disable that feature and delete or convert all volumes (that is, snapshots, repositories) associated with that feature before you replace the controllers. You can convert legacy Snapshots to the updated Snapshots feature. Before you upgrade a controller-drive tray, you should disable any premium features used on your storage array that are not supported on the new controllers.
