Migration from a PC to a Mac fails soon after startup. An error message appears: An error occurred while migrating the disks.

If you open the parallels.log file located in C:\Windows\Logs on the PC, you will find the following error messages:

    Read from FS snapshot failed: 
    ERROR CODE: 0x0010c45a:0x0000; 
    Error : Failed to read next block from DA snapshot, error 0x8103251
    Error: FS volume migration failed with error : 0x8103251 


Cyclic Redundancy Check (CRC) error. CRC errors appear when the transferred data is damaged.


  1. Make sure you have the latest update of Parallels Desktop installed.
  2. Make sure you have installed the latest version of Parallels Transporter Agent from the Parallels website.
  3. Check all hard disks installed on the PC for errors:

    • Go to Start > Computer.
    • Right-click on each hard disk installed on the PC > Properties > Tools > Check Now > Check both check-boxes and click "Start".
    • Restart the PC.
    • Wait until your hard disks are checked for errors (it may take some time).
  4. Start the migration again. Try to avoid using a Wi-Fi connection for the migration.
