Can you explain what you are trying to do with "^Learning": "PleaseWork\\\\Providers" and `"^Learning\\Iteration 1": "PleaseWork\NewIteration". The former is invalid, and the latter will only match that one Iteration and mapp it to another one!

Hello, thank you for responding so quickly, Yes of course. I had understood after reading online that the format was "^Area source\\\\sub-area": "Area Target\\\\sub-area" and "^Iteration source\\sub-iteration": "Iteration target\sub-iteration" For my source area the name is Learning only, I don't have any sub-areas so I thought that was the correct format. I am not sure I get the second question, I thought this was needed when doing the migration across projects with distinct iterations. When running the program I had an error saying I needed the node enricher I believe Em seg., 1 de jul. de 2024 às 15:00, Martin Hinshelwood nkdAgility.com ***@***.***> escreveu:
