Hi Andreas,
Thank you for your interest in Syncfusion Products.
We have prepared the sample to meet your requirement of “Copying the bookmarks from one document to another document along with the nested bookmarks content”. Please find the sample from the below link. In this sample we have used the BookmarkNavigator class to get the specified bookmark content (along with the nested bookmark content) and copied the content to the newly created word document. Try running the sample and let us know if this helps you.
Sample:
