Work Items Migration - Area & Iterations maps

[Chandu001729]

I have Source and Destination projects in different orgs and have different Area and Iteration paths as below and i have my configuration as updated below but facing the error as:

I am trying to the migration as below
I have two ADO projects in a same org, but few of the Backlog items are already migrated to destination project, now we have a requirement of migrating all the existing items which are in below states "Closed, Removed, Done, Released & Design" and the Area and Iteration maps need to be same as Destination it should not overwrite with source things and It should ignore if the work item is already present in the destination.

[07:57:19 WRN] [16.0.9] NOTE: It is NOT possible to migrate a work item if the Area or Iteration path does not exist on the target project. This is because the work item will be created with the same Area and Iteration path as the source work item with the project name swapped. The work item will not be created if the path does not exist. The only way to resolve this is to follow the instructions:

@MrHinsh requesting your help to achieve this process

[MrHinsh]

It looks from your config that you have not followed the instructions on https://nkdagility.com/learn/azure-devops-migration-tools/Reference/Tools/TfsNodeStructureTool/ for configuring the node mappings.

Note that mappings need double escaped:

"Mappings": {
      "PortfolioPM\\\\Sprint": "PPM-Migration\\ART 03\\Audit Workflow\\Integrations\\Integrations With PortfolioPM"
    }

Update: I have fixed the link in the message, and you can find the TfsNodeStructureTool listed in the left navigation on the site.
