# Convert storage groups to cascaded

Storage groups are a collection of devices that are stored on the storage system. An application, a server, or a collection of servers use them.

## About this task

This procedure explains how to nondisruptively convert a stand-alone storage group to cascaded storage group. Once complete, the original storage group serves as the parent to a new child storage group.

In eNAS operating environments, you can also perform this operation from Storage Groups for File page (System > System Dashboard > File Dashboard > File Storage Groups).

Before you begin:

- You must have Administrator or StorageAdmin permission.

1. Select the storage system.
2. Select STORAGE > Storage Groups.
3. Select the storage group, click , and click SG Maintenance > Convert to Cascaded.
