It depends :-) It starts with the bootloader: different hardware boots in very different ways. If you have GRUB (the default with Debian), you will need either a "traditional BIOS" or UEFI beneath it. That means MACs, Raspberry Pis and other misc hardware is out. Then, the kernel is built for a specific architecture family. A kernel built for x86_64 won't be happy on ARM. Or RISCV. Or... If your distro has taken those hurdles, you'll still be left with some funny things. Kernel modules for hardware you hadn't in your first motherboard. Network scripts might be set up to look for a specific MAC address which won't "be" in your new machine. Your fstab might be referencing file systems which have moved around (this is one of the cases where label based or UUID based file system referencing clearly "wins"). In the latter cases, chances are good that you'll get enough of your system up to "fix" things. Be prepared to invest some time, and to learn a thing or two :-) Cheers -- t
