Re: Damned useful!
I don't think any typical OS did a 32-bit to 64-bit switch with an OTA update. Usually, that kind of thing was done with a new edition that you installed manually. The chances of messing something up with your config would be quite high otherwise. Since they are compatible, you can load in the package repositories for the 64-bit version, update the bootloader and kernel from the packages or by extracting them from the image, and perform a no-reimage upgrade. If you break something, that's why they didn't do it that way when it's already pretty easy to write a fresh OS image to a card and transfer your config over instead.
