Default Does flashing kdz change partition?

Hi, i was thinking of updating my LG 2X from froyo to ICS. It is currently running CM7 and the previous stock rom was froyo. If i am not wrong the standard procedure is to use AIO (all in one) tool kit and flash kdz. I also understand that ICS uses a different partition layout. So is it okay for me to flash the V30B_00.kdz straight? I am guess it does the partitioning for me? Just wanted to be sure before proceeding. Many thanks in advanced.
