+Para poder hacer una migracion de los datos de devicehub-teal necesitamos varios ficheros csv con los datos.
+Por ejemplo:
+
+--csv-lots-dhid con la relación dhid con nombre del lote.
+--csv-dhid es la relación de dhid con uuid de un snapshot.
+--lots es la relación entre el nombre de un lote y el nombre del tipo de lote
+--snapshots es el directorio donde buscar los snapshots reales. Los busca por uuid
