Is it expected that zigpy not work after flash to MultiPAN firmware?

[MostHated]

Hey there, I flashed my Sonoff Dongle-E with MultiPAN RCP firmware, and later discovered the existence of zigpy. My current setup uses a TI CC2652R devboard, and I used zigpy to backup it's setup and I wanted to test and see if it was possible to use it to restore back to the new device, but I have not been able to get it to connect properly in any way, just trying to confirm if it see's it. I attempted to use the updated baudrate listed on the firmware update page of 460800, etc. I figured it was a good idea to check if this is expected behavior, and whether it would/should be working in the first place with this firmware.

Unfortunately, I didn't know about zigpy before I flashed the firmware, so I can't say whether it worked or not prior to now, but the flash seemed to work fine and I have no reason to believe that there is an issue, I was just hoping to test out if I could restore to it or not. If it is known that zigpy would no longer work with this firmware, that is perfectly fine, I just am hoping to know before I waste any more time on trying to get it to work.
