Check if mongo services still running, there are some:

root@giverny:~# date; ps aux | grep mongo
Thu Nov 18 09:19:20 CET 2021
grouss    3578 64.1  6.9 33059300 11395928 ?

@grouss stopped the services in question

Then the actual upgrade (roughly):

root@giverny $ apt upgrade -y
root@giverny $ reboot
root@giverny $ # Update sources.list references to buster
root@giverny $ sed -i s's/stretch/buster/g' /etc/apt/sources.list.d/*.list
root@giverny $ apt upgrade
root@giverny $ apt dist-upgrade
root@giverny $ reboot

And now giverny seems to refuse to boot back. Stopping a bit that part as I cannot check further yet.
I'll check the desktop machine physically tomorrow.
