When running a SharePoint Site Copy as powershell jobs on separate servers, you may experience a site copy failure with the error "“DataTable internal index is corrupted: 8” in the migration log.
This typically applies to very large Site sizes.
This is a known issue in Content Matrix.
The issue has been filed with Development, and is being investigated for a fix in a future release.
This appears to be an intermittent issue.
Try running the job again.
If still failing, change the source connection to a different Content Matrix adapter.
