Haven’t tried swapping completely different CPU brands, but if you have set up CPU microcode, you might want to uninstall that before swapping over.

For graphics cards, Intel and AMD drivers can exist side by side so you should be able to install the AMD ones before transplanting it over.

Other than that, it should be fine. And worst case you can always swap back!

By your maths it’s 10/50.01=19.99% nationalised, actually. :P

No opinion on Debian but as a heavy ArchLinux user I should point out you shouldn’t upgrade without reading the news as occasionally manual intervention is required. Upgrades can and will break things if you’re not careful.
