Your migration will be in your project and component that you defined in your target file. In addition to support review and approval, it is placed in a changeset (each module always gets it’s own changeset). Simply look for a changeset named the same as your Module.
The Module of interest is found in the root folder.
When you open a module you should see the same structure as your source DOORS Module.
Feel free to review the details of the mappings. You should look at the artifact types, the attribute types and values, and the hierarchy of the elements.
