Color problems with X6

Something has changed dramatically between X4 & X6 when printing color.

Using X4 right out of the box with no "tweaking" all pantone colors print perfect on Xerox 700 Digital Color Press.

Trying to print same pantone colors in X6 with no "tweaking"  on Xerox 700 Digital Color Press, color is not even close.

Is there a way to setup X6 to replicate color management of X4.

Thanks
