When performing a migration the following error is seen and the migration fails:
ERROR: [2614-215-1-80040E14] Unable to update auxiliary work item stats for run '{980912A7-20C7-4663-98B7-8B4C9D93C1D5}'.:
Possible causes for this are that the SQL server is unreachable or that the C drive on the migration console has run out of space.
Verify that the SQL server is reachable and that there is sufficient disk space on the migration console.
