This thread is to post that, in my experience, migrating from the default Debian to Devuan works without issue. I will note that you need to use Devuan ASCII, Beowulf will not let you upgrade properly. I have not extensively gone through to test features, I will post if I run into any issues.
Steps:
1. Install sysv init system
2. Reboot
3. Install WICD (this is temporary, and unnecessary if you know how to use wpa_supplicant)
4. Stop NetworkManager, and start WICD (or wpa and dhcpcd)
5. Change /etc/apt/sources.list from the default debian repo to deb.devuan.org/merged and change Jessie to ASCII
6. Purge systemd (this will also remove mate, lightdm, and networkmanager)
7. Apt update and install devuan keyring, by running 'apt-get --allow-unauthenticated' (there must be a better way to do this, but I don't know it)
8. Apt upgrade
9. Install NetworkManager, lightdm, eudev, elogind, and whatever de or wm you want
