15.5 Moving or Splitting Encrypted NSS Volumes

We strongly advise against using the Move Volume or Split Volume tasks for encrypted NSS volumes because of the following security considerations:

You can move or split data only to a newly created NSS volume. NSS encrypted volume support is available only for volumes created in NSSMU, so the target volume is necessarily an NSS volume that is not encrypted.
The data is transferred nonencrypted from the encrypted NSS volume to the nonencrypted target volume where the data is stored nonencrypted.

WARNING:If you use the Move Volume or Split Volume tasks on an encrypted NSS volume, the relocated data is stored nonencrypted in its new location. It is no longer secure.
