How to change OS from Debian to Ubuntu?
Is there any tutorial how to change OS? I want to switch Debian 6 to the latest Ubuntu (14.10x64). I guess I’ll have to backup all my sites (9) with MySQL databases somewhere, then recreate droplet with the same IP but new OS (Ubuntu) and restore all my sites. Is there most painless and quickest way to do that, cause I can’t keep my sites offline for a long time?
