Would it be possible to update the device to the new My Cloud Home platform? I can see why WD might not want to do that for some of their devices from a technical standpoint (not having the necessary hardware) but the EX2 is pretty comparable. I can also see why they wouldn’t want to do it from a business standpoint (make us buy another device).
What can I do to get the firmware updated to the My Cloud Home version?
Second, generally it is officially not possible to install one My Cloud model’s firmware on a different My Cloud model. Often the hardware is different and there are different features from one model to the next. Unofficially who knows, with the single bay My Cloud models it is possible to hack the model’s firmware to enable features or replace the firmware entirely with something different.
