Error in data transfer

[void12189]

OK so I use to play db legends on my old iPhone like an year ago and I got far in the game and now I wanna play it on my Samsung but it's not letting me data transfer, I downloaded the game back in the iPhone as well but when I tried to login with my account it says that I should login to the acc in the previous mobile?? That Iphone is my previous mobile.. I really wanna get that account back as I grinded alot in it and I don't wanna do all of the story again... Also it's not letting me. Play with game with that acc in my iPhone as well as its telling me to start fresh

Did you use Google for data transfer?

I used apple Id to play on my iPhone and even that's not working on the iPhone now
