I have dietpi installed on a j3455 intel nuc running flawlessly for more than a year.
Is there an easy way ( whiteout reinstalling everything ) to upgrade dietpi from Debian 9 to 10.
Everything I have installed is from dietpi software except nextcloud ( installed from source because of Debian 9 php version) and , openvpn and hp.lip
Have you tried updating the dietpi software within dietpi-launcher?
You can’t do a full base system upgrade from dietpi-launcher lol (afaik)
Edit: answered my own question from a post below . Sorry!
We do not support distro upgrades (no distro/OS does), it is simply too risky with unpredictable outcome. However you can do it manually, at best after doing not only a dietpi-backup but a full SDcard/drive clone.
sed -i 's/stretch/buster/g' /etc/apt/sourcess.list
sed -i 's/stretch/buster/g' /etc/apt/sourcess.list.d/*.list
