Hello everybody! I have a client who is still using the installed ISPConfig version which is old one v3.2.2. I cannot find out the correct information about, so kindly may I use this topic to ask is it okay to upgrade from 3.2.2 to 3.2.7p1 manually, furthermore should I directly go to v3.2.7p1 or I might have to go gradually to v3.2.3, v3.2.4, v3.2.5 ... and finally v3.2.7p1? May I also ask, if version 3.2.7p1 works on PHP 7.4? Client currently v3.2.2 works on PHP 7.3 which is "EOL" so I would have to switch this too. My last question, is it possible to add IPv6 to ISPConfig? Currently, client has got Linux Debian 10 machine already working on IPv6, but I do see only IPv4 being added to the "server IP" using the ISPConfig interface. Thank you in advance for feedback information!
It should work just fine upgrading ISPConfig 3.2.2 to 3.2.7p and php 7.4 is supported as additional php but one must maintain php 7.3 as default php if one is Debian 10.
Thank you for information. In terms of switching from 7.3, I wanted to do this after I upgrade ISPConfig. That way, I would have all websites working on 7.4 including the ISPConfig and would switch the PHP default version to 7.4 -> if that would be a good thing?
Use Additional PHP Versions for websites, then you can set them to whatever version is appropriate for the site. Regarding the system php version, the only version supported on a given OS is the default for that OS, not one that you upgrade to. Changing the default OS version is a frequent source of problems. (At the same time I will say that I have chosen to run systems with an updated system php version at points in the past, knowing I was responsible for and, most importantly, ready to diagnose and resolve any issues that arose from doing so. I have not tried 7.4 on a Debian 10 system. I have upgraded Debian 10 systems to Debian 11 with good success, and ran 7.4 there.)
In short, php7.4 only works as additional php in Debian 10 i.e. for websites usages only, but default php7.3 must be kept for ISPConfig to work with your server. ISPConfig will definitely fail to work if you changed default php from 7.3 to 7.4. For upgrading the OS version, the effect is the same as Debian 11 come with php7.4 as its default php so one must keep it as default php. ISPConfig will definitely fail to work with your server if you changed default php in Debian 11 to other than php7.4.
