Transfer saved games from pirate license (Dark Souls 3)

Played in the pirates from the day the game was decent, bought the license. Is it possible to transfer save from the pirates for a license on steam version of the game? Tried to transfer the save file DS30000.sl2 with a replacement on the way C:\Users\....\AppData\Roaming\DarkSoulsIII but in the game when you load save issues that she can't download it, maybe there's a fix or a program that fixes this?
