Is anyone familiar with the differences between International Weather Energy Consumption ( IWEC) and IWEC2 files?

IWEC is still available by the DOE and EnergyPlus website for energy simulation while IWEC2 are sold by ASHARE.

Are they both reliable to be used for building energy simulation? if not Do we need to repeat all building energy simulations with the new sets of data (IWEC 2) to achieve better results?
