Am I Scr3wed? - switching to new iphone

Post deleted by me. Game Center was the issue. Funny as I had a 4s many years ago tied to game center a. Then I moved to a 5s tied to game center b with NO issues and no changing of game center per my remembrance. Now, I'm moving to a 6 and imported both a and b profiles from Apple. Had no issue on my other games (just Modern War and Crime City). Needed to log out of the Game Center that was on my 5s for 4 years and back to the old one from over 4 yrs ago to get the connection.
