ATC V1 magazine upgrade capabilities

I have one V1 ATC magazine. I am looking to expand add another magazine. It is my understanding that the V1 and V2 magazines are not compatible. With that being the case, is there a way to upgrade the V1 to a V2 or do I need to sell my V1 and purchase two V2 units? If that is the case, I will have a V1 setup with the QCW mount available for sale.

I believe the RTCNC controller (if that is what you have) allows you to select which Easy ATC version you are using in each separate setup. This handles the different Z offsets used by different versions. I am not sure about the Masso/Buildbotics.
