I don't really understand your question. If you have uploaded a TANE route onto the DLS then it would also be available in TRS19. Most (if not all) TANE routes work perfectly well in TRS19. If you have not uploaded it to the DLS then you can do a direct transfer.
In TANE CM select the route, right mouse click and select Export to CDP. Specify a filename, a drive and folder to store the file.
In TRS19 CM open the File menu, select Import Content Files, navigate to the drive, folder and filename specified above, and click open.
