Hi, I'm using ISPConfig ver 3.0.5.4p9 on Ubuntu 14.04.4 LTS. Can I upgrade the OS to Ubuntu 16.04 LTS without losing my setup? I'm having a multi server setup. CP, web, mail, NS1, NS2; each is on a dedicated Ubuntu 14.04.4 LTS node.
Read this https://www.howtoforge.com/community/threads/ispconfig-version-for-16-04-lts.73526/#post-345913 a part of the notice: "The ISPConfig old stable 3.0.5p9 version can not be used on Ubuntu 16.04 as it is not compatible with PHP 7."
