I got it. Thank you all. I have been speaking with the support team and they will be transfering my data. :)
1. Main knight's name and level2. Names of other knights (3 other knights is enough)3. Friend code of the account you are trying to recover4. Guild information (if you were in a guild at any point)5. Armor your main knight is wearing.6. How many gems you have on your old account.7. Friend code on the NEW device or on your new knight.8. ANDROID users : receipts or transactions if applicable
I can't see why not. although keep in mind you can only transfer the accounts once every 24 hours ( maybe twice) it has been a while since i have been locked out seeing as don't transfer my account often.
