## Renaming devices and groups

You can change the display names of devices and groups without losing any of the real-time or historical data associated with them.

Group and Name are separate columns.

The Name column is always displayed.

The Group column is displayed by default, but you can use the Column Selector to remove it from the display area. You can now drag and drop the Group column to the Group By Box area to show the devices organized within each group.

System Name and Data Availability are new columns that you can select for inclusion in the display area.

System Name shows the internal name in `group.name` format.

Data Availability indicates All for devices that are active and have real-time and historical data, and Historical only for devices that have been deleted and only provide historical data. Historical devices are included in the devices displayed when you select the Show historical devices checkbox.

The Show historical devices option displays devices that have been deleted . Since the data for these devices still exists in the system, they can be displayed when you select this option.
