An error occurred in the Migration Tools causing it to stop! This is likley due to a configuration issue and is not being logged remotely. You can always ask on https://github.com/nkdAgility/azure-devops-migration-tools/discussions
MigrationTools.Exceptions.MigrationToolsException: Unable to load Common Structure for Target.This is usually due to TFS having a different installed langauge version than was expected.. Validate that 'Area' is the correct name in your version. This would be something like 'Fläche' or 'Aire'. If you open the area tree in Visual Studio, or web access, you should see the name your langauage uses for 'Area' or 'Iteration. Do not try to add a specific area or iteration path to this field. Check the defaults on https://devopsmigration.io/Reference/Endpoints/TfsTeamProjectEndpoint/ for an example fro English.

[MrHinsh]

This either means that you are connecting to a non-english language version of TFS, or the project name is incorrect.

@MrHinsh I am sure i am using english language. I can see Areas and iterations on project configuration screen and project name is correct. I used "Project": "TSProject1", "Project": "Project2", Can you please check my configuration.json.
For version 16.2.9 is there any changes for LanguageMaps.

@MrHinsh Below are the debug errors.

Have you tried feeding your config through devopsmigration upgrade -c XXXX?
