Errors with WorkItemMigrationConfig Processor

Question

We are using the Azure DevOps OSS Migration tool and we watch the video and links.

We are migrating from one Azure DevOps organization to another organization.

We constantly encounter issue like below and the migration tool is halt.

Error:
[16:02:15 INF] [Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemLinkValidationException: TF201066: You cannot add a Child link to work item 9690 because a work item can have only one Parent link. ---> System.Web.Services.Protocols.SoapException: TF201036: You cannot add a Child link between work items 9815 and 9690 because a work item can have only one Parent link.

I am using Version 10, in my configuration.json, I just useNodeStructuresMigrationConfig and WorkItemMigrationConfig processors.

"QueryBit": "AND  [Microsoft.VSTS.Common.ClosedDate] = '' AND [System.WorkItemType] NOT IN ('Test Suite', 'Test Plan')",

I migrate all open work items, then migrate the closed work items. Sometimes during migrating closed work item, the migration tool would create a duplicated parents and empty work item.

Here is my configuration.json:

{
      "ObjectType": "MigrationTools.Core.Configuration.Processing.WorkItemMigrationConfig",
      "ReplayRevisions": true,
      "PrefixProjectToNodes": false,
      "UpdateCreatedDate": true,
      "UpdateCreatedBy": true,
      "BuildFieldTable": false,
      "AppendMigrationToolSignatureFooter": false,
      "QueryBit": "AND  [Microsoft.VSTS.Common.ClosedDate] = '' AND [System.WorkItemType] NOT IN ('Test Suite', 'Test Plan')",
      "OrderBit": "[System.ChangedDate] desc",
      "Enabled": true,
      "LinkMigration": true,
      "AttachmentMigration": true,
      "AttachmentWorkingPath": "c:\\temp\\WorkItemAttachmentWorkingFolder\\",
      "FixHtmlAttachmentLinks": false,
      "SkipToFinalRevisedWorkItemType": false,
      "WorkItemCreateRetryLimit": 5,
      "FilterWorkItemsThatAlreadyExistInTarget": true,
      "PauseAfterEachWorkItem": false,
      "AttachmentMazSize": 480000000,
      "CollapseRevisions": false,
      "LinkMigrationSaveEachAsAdded": false
    }

Can someone please provide some light on the error?

Thanks, Dennis

You might misconfigured the Migration tracking field ReflectedWorkItemId, which caused above error. You can refer to this document to check the actual name of the ReflectedWorkItemID field. Check this issue here for more information.

For the duplicated parents issue. There has been an issue reported here, you can follow it up.

You can try migrating the all the work items at one time. Because in my test, If i first migrate the open work items, then migrate the closed work items. I will lost the parent and child links in the migrated closed work items.
