The base line i've did this with is ERPNext 12 on Debian 9 with Python 3.5. We use nginx as a reverse proxy frontend with letsencrypt certificates. 

We need to upgrade this to ERPNext 12 on Debian 10 with Python 3.7.

First make a snapshot if you are running it in a VM. This makes it much easier to rollback after it fails.

apt-get update
apt-get upgrade
apt-get dist-upgrade

Do not do an apt-get autoremove because this will remove python 3.5 and this will make the next step hell.
