You need your source database encryption passphrase or encryption key when you perform the pre-migration task. If you do not know your passphrase or key, you can retrieve the encryption key before you start the task.


  1. Log in to a vCloud Automation Center 5.2 Manager Service Data node as the system administrator.
  2. Open a command-prompt window.
  3. Navigate to and run the following EncryptionKeyTool command using a single command line.
    C:\Program Files (x86)\VMware\vCAC\Server\ConfigTool\
    key-read -c "C:\Program Files 
    (x86)\VMware\vCAC\Server\ManagerService.exe.config" -v

    The retrieved encryption key appears, for example: Xjl1Tjk3WBOF6YaZoxWxaBmRUGhmwLZ50jJgynBSHU0=.

  4. If you are running the pre-migration task now, return to the pre-migration Database Security screen and enter the retrieved encryption key in the Encryption key text box to continue with pre-migration. Otherwise, record the key value for later use.
