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.
