Thanks for contacting support.

You may please use Aspose.Facades.AnnotationEditor.ExportAnnotationsXfdf() method to export annotations from your PDF file. Later you can import exported file for your replica using ImportAnnotationsFromXfdf() method. Please check following sample code snippet:

string[] gAnnoType =
            {
                AnnotationType.Caret.ToString(),
                AnnotationType.Circle.ToString(),
                AnnotationType.FileAttachment.ToString(),
                AnnotationType.FreeText.ToString(),
                AnnotationType.Highlight.ToString(),
                AnnotationType.Ink.ToString(),
                AnnotationType.Line.ToString(),
                AnnotationType.Link.ToString(),
                AnnotationType.Movie.ToString(),
                AnnotationType.Polygon.ToString(),
                AnnotationType.PolyLine.ToString(),
                AnnotationType.PrinterMark.ToString(),
                AnnotationType.Screen.ToString(),
                AnnotationType.Popup.ToString(),
                AnnotationType.Square.ToString(),
                AnnotationType.Squiggly.ToString(),
                AnnotationType.Stamp.ToString(),
                AnnotationType.StrikeOut.ToString(),
                AnnotationType.Text.ToString(),
                AnnotationType.TrapNet.ToString(),
                AnnotationType.Underline.ToString(),
                AnnotationType.Watermark.ToString(),
                AnnotationType.Widget.ToString()
            };
var pdfDocument = new Document(dataDir + "BE.FC.01.WP.01.pdf");
Facades.PdfAnnotationEditor editor = new Facades.PdfAnnotationEditor(pdfDocument);
MemoryStream vOutputStream = new MemoryStream();
editor.ExportAnnotationsXfdf(vOutputStream, 0, 1, gAnnoType);
var fs = new FileStream(dataDir + "annots.xfdf", FileMode.Create);
fs.Write(vOutputStream.ToArray(), 0, vOutputStream.ToArray().Length);
var doc = new Document(dataDir + "replica.pdf");
fs.Close();
vOutputStream.Close();
editor = new Facades.PdfAnnotationEditor(doc);
doc.ImportAnnotationsFromXfdf(dataDir + "annots.xfdf");
editor.Save(dataDir + "Imported.pdf");

In case you face any issue, please share your both PDF documents with us. We will test the scenario in our environment and address it accordingly.
