The recommended way is a clean install of Bullseye on the Pi 5, but then
you get Wayland, Network manager and no rsyslog, and you'll have to sort
that lot out.

If the Pi 4 is using a 64 bit version of Buster, you can upgrade in
place despite the warnings.

If it is only running 32 bit Buster, then it's a bit more involved.

BTW; a USB SSD, as it will be vastly faster than a mechanical disc for
running software. Keep the spinning rust for data.
