== Upgrade to testing ==

Basically (as root):
 su -

 apt-get update && apt-get upgrade -y
 cat <<EOF >/etc/apt/sources.list
 deb https://deb.debian.org/debian testing main contrib non-free
 deb https://deb.debian.org/debian-security testing/updates main contrib non-free
 EOF
 apt-get update
 apt-get dist-upgrade -y
 apt autoremove -y

Then answer the questions.

If you enable extra architectures (see below), you might want to limit the architectures of the main repositories to amd64 (if you use that). So do this instead:

 apt-get update && apt-get upgrade -y
 cat <<EOF >/etc/apt/sources.list
 deb [arch=amd64] https://deb.debian.org/debian testing main contrib non-free
 deb [arch=amd64] https://deb.debian.org/debian-security testing/updates main contrib non-free
 EOF
 apt-get update
 apt-get dist-upgrade -y
 apt autoremove -y

== Make apt prefer testing by default ==

If you are going to use multiple repos (e.g. debian-ports below), make testing the default like so:

 echo 'APT::Default-Release "testing";' >/etc/apt/apt.conf.d/91prefertesting

== Add support for new (hardware) ports ==

If you want to add support for new ports (e.g. RISC-V), do this:

 apt-get install -y debian-ports-archive-keyring
 cat <<EOF >>/etc/apt/sources.list
 deb https://deb.debian.org/debian-ports unstable main
 deb https://deb.debian.org/debian-ports unreleased main
 deb https://deb.debian.org/debian-ports experimental main
 EOF
 apt-get update

Consider limiting the new ports to a specific architecture. Also consider limiting the main repositories to amd64 (if you use amd64). So do this instead:

 apt-get install -y debian-ports-archive-keyring
 cat <<EOF >>/etc/apt/sources.list
 deb [arch=riscv64] https://deb.debian.org/debian-ports unstable main
 deb [arch=riscv64] https://deb.debian.org/debian-ports unreleased main
 deb [arch=riscv64] https://deb.debian.org/debian-ports experimental main
 EOF
 apt-get update
