Hello, Since I don't find any solutions to upgrade debian 7 to debian 8 without any problems, I search for a tutorial or some explanations for a migration about apache2 to nginx on a debian 7 version. Why ? Since the begining, I would like to use the http2 protocol (with apache2.4 or nginx 1.9). But on debian 7 apache 2.4 is not really compatible, so on different forums, people advice to upgrade the Debian 7 to 8. So I try to upgrade my debian 7 but it failed, see this thread : https://www.howtoforge.com/community/threads/debian-8-ispconfig-3-1-apache-2-4.75334/ I am still running a Debian 7 with an apache2 without http2 protocol, so I think the best is to continue on debian 7 but migrate to nginx that can use http2 protocol and who have a compatible version with Debian 7. What do you think guys ? Do you have some ressources about this ? Is it possible with a Ispconfig 3.1.2 ? Thank you and have a nice day.
