"backup and restore" to migrate from one Zigbee coordinator HW adapter to other hardware?

[Hedda]

This idea came from developer discussion between zigpy-znp developers in https://github.com/zha-ng/zigpy-znp/issues/10

Would it be possible to script a "backup and restore" migration feature/function built into zigpy radio libraries that allow users to relatively easily migrate from one Zigbee coordinator hardware adapter to a other Zigbee coordinator hardware adapter if use same radio library and maybe even if they are not using the exact same hardware MCU chip model/module?

Migrations such as these could become common as new more powerful adapters become available:

• Any CC2530 based adapter hardware -> Any other CC2530 based adapter hardware
• Any CC2531 based adapter hardware -> Any other CC2531 based adapter hardware
• Any CC2538 based adapter hardware -> Any other CC2538 based adapter hardware
• LAUNCHXL-CC26X2R1 development board -> Zig-a-zig-ah (ZZH) CC2652R1 based adapter
• LAUNCHXL-CC1352P-2 development board -> Zig-a-zig-ah (ZZH) CC2652R1 based adapter
• LAUNCHXL-CC26X2R1 development board -> LAUNCHXL-CC1352P-2 development board
• Any CC2652R based adapter hardware -> Any CC2652P based adapter hardware
• Any CC2652R based adapter hardware -> Any CC1352P based adapter hardware

Would be a more awesome feature if could also migrate from older TI chips to newer TI chips:

• Any CC2530 based adapter hardware -> Any CC2531 based adapter hardware
• Any CC2531 based adapter hardware -> Any CC2538 based adapter hardware
• Any CC2530 based adapter hardware -> Any CC2652 or CC1352P based adapter hardware
• Any CC2531 based adapter hardware -> Any CC2652 or CC1352P based adapter hardware
• Any CC2538 based adapter hardware -> Any CC2652 or CC1352P based adapter hardware

Would really be an awesome feature to have if could be made user-friendly for integration like ZHA!

https://github.com/zha-ng/zigpy-znp can backup and restore NVRAM on same type of adapters.
