Scheduled Migration Tasks Fail with Communication Error

MGD-MSG-0440 A communication error occurred with host <host name> on port <port number>. Verify that the Series 7 migration server name and port number are correct.

When more than one migration task is scheduled to run at the same time, one task fails. The error appears in the failed task's run history details.

To work around the problem, schedule the migration tasks to run in sequence.
