How to Upgrade Data in a Multilevel Dataset

Language:

Multilevel datasets in Trusted Extensions ease the task of relabeling files. For more information about multilevel datasets, see Multilevel Datasets for Relabeling Files in Trusted Extensions Configuration and Administration.

Before You Begin

You must be authorized to relabel files. You can operate at two or more labels, one of which dominates the other.

A multilevel dataset is mounted in at least one of the labeled zones, and the mount name is identical, such as /multi, in every zone that mounts the dataset.

To permit relabeling, your administrator must have completed the following tasks:

How to Create and Share a Multilevel Dataset in Trusted Extensions Configuration and Administration
How to Enable Files to Be Relabeled From a Labeled Zone in Trusted Extensions Configuration and Administration
How to Enable a User to Change the Security Level of Data in Trusted Extensions Configuration and Administration

You must be logged in to a multilevel session.

Create a workspace at the higher label.
For example, to upgrade a file from PUBLIC to INTERNAL, create a workspace at the INTERNAL label.

For details, see How to Add a Workspace at Your Minimum Label.
Open a terminal window and list the directory that contains the file to be upgraded.
In this example, the filename is temppub1.
```
$ ls /multi/public
temppub1
```

Relabel the file.

$ setlabel "cnf : internal" /multi/public/temppub1

Verify the label change.

$ getlabel  /multi/public/temppub1
/multi/public/temppub1: "CONFIDENTIAL : INTERNAL USE ONLY"

(Optional)Move the file to a directory at the target label.
```
$ mv /multi/public/temppub1 /multi/internal/temppub1
```
