9800 Piezo Pro inkset into a 9900

Hello
I am in the process of moving my Piezo Pro inks from a 9800 to a 9900.
Of course the 9800 is a 8 colour machine while the 9900 has 11 channels.
I do not have the Warm:Very Light and Cool:Very Light inks
Can i just put PiezoFlush into the Orange (Warm:Very Light) and Green (Cool:Very Light) channels?
And then just use the 9890 curves?
Is that the recommend procedure? I have looked on the forum and instruction manual and don’t see where this question is answered,
Thanks
Neil

The easiest method would be to install the 7900-9900-Pro-K4 curves which do not include the VLGs or the O & G channels… and yes, install PiezoFlush in O & G

Ok great thanks, yes that makes sense
