I am running a production server, so this is why I want to ask first before I destroy something. When I installed, the latest version of PHP supported by Debian was 8.1. Now we have 8.2 and 8.3. In my /etc/php folder I have 5.6 through 8.1, which all have cgi, cli, fpm folders within them. The folders 8.2 and 8.3 only have the folder cli with in them, I gather I have to install PHP and FPM-PHP for both 8.2 and 8.3 but I want to know the correct way to do this so I don't break ISP Config and the result being that 8.2 and 8.3 are available.
Ah, thanks a million. I tried searching the howtoforge main page but maybe I was using the wrong query strings.
