 * My migration tool hangs when copying uploads. Database finishes, but media transfer
   never completes. Is there a chunk size or resume option?

 * Hello,
 * Please apply the following WPvivid settings and try running the auto-migration
   task again.
 * General settings:
    1. Uncheck the option of ‘Merge all the backup files into single package when a
       backup completes’
 * Please go to WPvivid plugin settings tab page and set up the configurations below:
 * Advanced settings:
    1. Database access method: PDO
    2. Compression method: PCLzip
 * Backup performance mode: Custom
    3.  Compress files every: 100 MB
    4.  Exclude the files which are larger than: 200MB
    5.  PHP script execution timeout for backup: 300 seconds
    6.  PHP memory limit for a backup task: 512 or 1024 MB (ensure it is higher than
        the total size of your database)
    7.  The number of files compressed to the backup zip each time: 300
    8.  Split a sql file every this size: 100 MB
    9.  **Chunk size : 512 KB**
 * After applying these changes, please let us know if the auto-migration completes
   successfully.
 * Alternatively, you can create a backup of your source site and manually upload
   it to the target site to perform a restore.
 * Kind regards.
