Hello,

I’m trying to migrate a project to another one and they’re using the same process. Meaning all the work item types are the same and are coming from one source. So all the work item types should exist in both project. When I run the migration tool I get this error regarding one of the work items.:

Error while running WorkItemMigration
Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemTypeDeniedOrNotExistException: TF201077: The work item type Task cannot be found. It may have been renamed or destroyed.

I tried all the previous solutions regarding this issue but none of them have worked. I’m not using Visual Studio or anything. Just the ADO Migration Tool.

And this is my config file - I changed some names for security reasons of course:

After I run the ADO Migraiton tool, it creates all the iterations and paths and areas, but only when it reaches to that specific work item it stops working. I would appreciate your answers and solutions regarding this issue.
