text: Figure 12-81 Create an encrypted volume by selecting an encrypted pool 
  
  You cannot change an existing unencrypted volume to an encrypted version of itself 
  dynamically. However, this conversion is possible by using two migration options: 
  
  (cid:2) Migrate a volume to an encrypted pool or child pool. 
  (cid:2) Mirror a volume to an encrypted pool or child pool and delete the unencrypted copy. 
  
  For more information about these methods, see Chapter 7, “Volumes” on page 241.
