Issue with Test Plan Migration - The value of field 'EndDate' must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM - azure-devops-migration-tools

Question

I have moved all test cases from TFS to Azure DevOps and now I am running Test Plan migration with tool version 11.6.8 and I encountered an error.
Does anyone know how to fix this? Any help is appreciated.
My Test plan migration config:
"Processors": [
{
"ObjectType": "TestVariablesMigrationConfig",
"Enabled": true
},
{
"ObjectType": "TestConfigurationsMigrationConfig",
"Enabled": true
},
{
"ObjectType": "TestPlansAndSuitesMigrationConfig",
"PrefixProjectToNodes": false,
"Enabled": true,
"OnlyElementsWithTag": null,
"TestPlanQueryBit": null,
"RemoveInvalidTestSuiteLinks": true,
"FilterCompleted": false
}
],
Here are the error:

In AzDO process template, I have set EndDate and Start Date to "Set the initial value to the current date and time", but I still encounter this error.
It looks like the error is about saving TFS Test plan? Do StartDate and EndDate fields exist in TFS test plan as I can't seem to find them.

Answer 1

I was able to figure out the issue. The test plan in TFS does not have StartDate and EndDate filled. Someone with right right access filled in the fields in TFS and migration does not encounter this error anymore.
