Transfer saved games from pirate license (Watch_Dogs 2)

All kind time of day! I can't find information on how to transfer the save file for the game Watch Dogs 2 (made for pirates CPY) to license Uplay account. For example, in the case of the game Assassin's Creed Odyssey managed to do that, using special utility that copied the User ID inside the save game on the right, and then he was picked up. As I understand it, it could be done and saves for Watch Dogs 2, but would understand what to edit. Please share experience...
