Cloned Server HDD and added PHP 7.1.6, plan to upgrade to Debian 9 As the title says! I cloned the Server HDD with HDClone 5 and that worked well. After done that, I connected that cloned HDD and disconnected the 'Master'! Everything just works fine after starting. I then added PHP 7.1 to the system using Till's Tutorial "How to install PHP 7.1.6 ...." and all went well, no error's etc.! So, the next step I plan is to upgrade firstly Debian 8.7.1 to Debian 9 Stretch, following to upgrade ISPConfig 3.1dev to the latest version 3.1.5! I read about the needed steps on this site and like to ask the experts to check the command I like to use are correct, and, for sure, are complete and workable. OK, here we go, Step 1: Change the name of the OS from 'jessie' to 'stretch' in /etc/apt/sources.list using: Code: nano /etc/apt/sources.list Step 2: The next commands are: Code: apt-get update apt-get upgrade apt-get dist-upgrade Are those commands correct, and, could I use the above as one command, or need it be done separately? Are there any more commands for to be done for the Debian upgrade? Step 3: The ISPConfig Upgrade from 3.1dev to 3.1.5 Code: ispconfig_update.sh I'll follow the 'How to update ISPConfig' tutorial I'll try that on that cloned Server HDD first before do the same on the Master for to be sure all will work correctly. If I need to do anything else, please let me know, because I'm not a Linux Expert at all! Thanks a lot for any comment and help.
