New Iphone--> Profile movement?

So, as we are all excited for getting the new iPhone and what not, I wanted to know the easiest way besides sending a ticket to glu as they take a long time to reply back, to transfer my account easily from my old iPhone to the new one I will be getting soon, I don't want to lose any of my data as I have worked hard on my account and so have many other players in EW3 who are probably in a similar position to me.

Also I hope that glu make the game compatible with ios8 and use it to make improvements to the game which include less lag in pvp... E.t.c...

Thanks
