Easy.... Save the firmware or firmware and user data to a USB drive then load on the new unit. All microHD's are identical hardware components (chipset, tuner, flash, etc.).
I can confirm this works perfectly.
The ONLY thing you want to always make sure you NEVER do on the MicroHD, is NEVER, EVER delete a satellite from your list, without FIRST deleting all the scanned-in channels on that sat first!
It'll boot-loop, and the only fix is to buy a cable for the internal serial port header, and reflash it. Instructions are posted in the receiver forum.
