I'm using Zorin Core 15 already for few months and I'm really happy with it as i have needed something what can easily boot from external drive, where you can easily encrypt and something what looks decent out of the box.
So all good here - however when i was first installing the OS, the Core 16 simply could not be deployed on the USB stick, once etched - the stick was not recognized for boot, so i had to go back a bit to Core 15 no complains - but the newer version looks even bit better so i would like to try that with the new build number 4.
However -> i don't want to loose all my settings and configs so the big questions is is there any official or unofficial guide how to upgrade?
I know how to do this manually and i have NAS where i could backup all my fstab configs, etc.... but i really dont want to burn my time on this. I'm looking for 2hr job, tops.
