I submited a code, in the old system I got AC and now with the new system I got WA...
may this be possible?

it can be possile.
cause new system may be change a lot in critical judge data, time limit.
You can read the new system problem statement and compair with your code also put all sample judge data found in this board.

I had a similar problem. For problem 10014, which I got PE and the new judging policy considers it as a Not-Solved, I tried to resubmit it, It was written in Ansi-C and I got RE, after changing the compiler to C++ I got AC. It was weird.
I don't know why this happened? This code just uses a very simple fixed size array.

I had already got PE in the 10894. But after resubmitting to the new Judge System I got WA. I don't think it is due to Compiler because the code has just some simple fors. How could a compiler change the behavior of some fores? I think there is a serious problem somewhere in this new system.
I don't think they have changed all of the testcases for all the problems. May be there is some problems in their comparison for deciding between AC or PE.

the compiler can change the behaviour of anything.
About PE -> WA...the algorithm of jufging PE's is different. Anyway, PE is equivalent as WA so that's not too much change...
