Is there a way to transfer the folder structure to the SharePoint libraries?
Migration variables.
For QuickPlace and Domino.Doc, yes. For normal Notes databases, probably not.
In general you can map any piece of Notes data (for example the Categories field) to a Folder column in your target data definition. Unfortunately, "folder" is not a piece of information that you can get from a item on a Notes document or from a folder. So perhaps there is some existing data item in your documents that you could use for this purpose.
