For /, /home, ... it's simple copy. Since you're using external USB, don't use "dd". "cp -a" should be good enough. Or, "tar -cf -". Never used "cpio".
For /boot, it's different can of worm. You can copy over the content, but you have to update /boot/efi/EFI/DistroX/, so that your motherboard "BIOS" knows about it. I'd recommend, install your distro on the new SSD using UEFI. Then, update files for your old kernel. That way, the structure is created for you.
Personally, I don't like UEFI. If you change motherboard, you can't boot. Personal experience!
You can if you have a bootloader installed at the default path. That's why UEFI bootable USB keys work fine. So if your disk has /efi/BOOT/BOOTX64.EFI then it should auto boot on any UEFI motherboard. /efi being the ESP boot partition. Booting something else requires an entry in the UEFI NVRAM. -- Len Sorensen
