Migrating a GuardPoint to a Different LDT Policy

Please Note:

Migrating a GuardPoint to a Different LDT Policy

To change the LDT policy that an LDT GuardPoint uses, complete the following steps to ensure that the GuardPoint is migrated properly from one LDT policy to another LDT policy.

Note

This procedure is for the migration of local file system GuardPoints only. For information about migrating NFS GuardPoints to clear_key, see Migrating GuardPoints over NFS from or to an LDT Policy.

Scenario

The GuardPoint is currently attached to LDT-Policy-1, which rekeys from clear_key to LDT-Key-1. The objective is to migrate the data in the GuardPoint to another versioned key, LDT-Key-2. Migration to LDT-Key-2 requires detaching the GuardPoint from LDT-Policy-1, and then attaching it to LDT-Policy-2 , assuming LDT-Key-2 is the versioned key specified in LDT-Policy-2. To do so:

  1. Clone the latest version of the key LDT-Key-1 to a non-versioned key such as LDT-Key-1-Clone.

    1. From the Products page in the CipherTrust Manager Console, click Keys in the left hand pane.

      Tip

      To navigate to the Products page from anywhere in the CipherTrust Manager Console, click the App Switcher icon in the top left corner.

    2. Click the name of the versioned key that you want to clone.

    3. In the Key Details area, find the version that you want to clone.

    4. Click the (...) button at the end of the row and select Clone to clone the selected version of the key.

  2. Identify or create a new versioned key that you want LDT to use to re-encrypt the data. For example, LDT-Key-2.

  3. Create a new Live Data Transformation policy that specifies LDT-Key-1-Clone as the Initial Key and LDT-Key-2 as the Transformation Key.

  4. Make sure that all data transformation has completed on the GuardPoint. To verify this, use the voradmin ldt attr get <GuardPoint> command.

  5. In your key manager, unguard the GuardPoint.

  6. On the host, remove the existing LDT attributes on the GuardPoint using the voradmin ldt attr delete <GuardPoint> command.

    voradmin ldt attr delete /oxf-fs1/gp1
LDT metadata has been removed from all files in GuardPoint [/oxf-fs1/gp1]
LDT attributes deleted from 10 files in /oxf-fs1/gp1
LDT: Metadata has been removed from all files in guard point [/oxf-fs1/gp1]

  7. Guard the directory using the new LDT policy.

    • If you have selected Auto Guard, data transformation begins as soon as the host gets the new policy information from the key manager.

    • If you have selected Manual Guard, use the secfsd -guard <GuardPoint> command on the host to begin data transformation.
