Hi,
inlined you will find the transcript of the migration
of a fully updated Debian Buster 10.9 VM with
gnome-desktop to Devuan Beowulf 3.1 with gnome-desktop.
Some steps could be optimized and improved, but its late....
during all the migration network was functional and just
a few packages were removed. Hope this helps.

Ciao,
Tito

Starting with fully updated Debian 10.9 VM

root@debian:~# nano /etc/apt/sources.list

Add to /etc/apt/sources.list

deb http://deb.devuan.org/merged beowulf main
deb http://deb.devuan.org/merged beowulf-updates main
deb http://deb.devuan.org/merged beowulf-security main
#deb http://deb.devuan.org/merged beowulf-backports main

(I did not remove buster repos yet, maybe it was an error
but I'm to tired to test it now but added pinning)

Add to /etc/apt/preferences.d/beowulf

Package: *
Pin: origin "deb.devuan.org"
#Pin: origin "deb.devuan.org/merged"
Pin-Priority: 900

apt-get update --allow-insecure-repositories
apt-get install devuan-keyring --allow-unauthenticated

Installing new version of config file /etc/debian_version ...

Configuration file '/etc/issue'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
