Fresh install and keep droplet snapshot on Old Ubunt 14
I have a droplet with an old version of Ubuntu: Ubuntu 14.04.6 LTS as web server LAMP.
I tried a do-release-upgrade but it didn’t work so I had to restore a snaphost.
I would like to make a fresh install of Ubuntu 18 LTS but keep my snapshot in case I can’t reinstall it or I have troubles to restore mysql databases.
How to make a fresh install of the last LTS Ubuntu and keep my snapshot ?
