Hello, I have a multi-server installation (2 DNS, 1 MAIL, 1 DB and 1 WEB) with an old ispconfig 3.1.12 installation This 5 servers are in old DEBIAN 7.11 version I would like to recreate a platform with the latest DEBIAN and the latest version of ISPCONFIG. I am not considering upgrading the current servers but rather building a new platform. If the DNS, MAIL or DB part does not scare me much, the most problematic part is the WEB part with the PHP version and especially the applications that run on it. On DEBIAN 7.11 it is PHP 5.4.45 that runs I plan to buy and use ISPConfig Migration Toolkit What approach should I have for the web part because I do not necessarily have control over the PHP pages developed and it is not possible to qualify everything on the latest DEBIAN 12/PHP version? I considered 2 approaches: - a brand new web server and keep the old web server with DEBIAN 7.11 and PHP 5.4.45 with a management of the 2 servers by the latest version of ISPconfig. Is it possible? (with the disadvantage of still having a DEBIAN 7.11 which no longer receives updates in the batch of servers to manage) - a single brand new server, but with several versions of PHP, that of DEBIAN 12 + addition of the PHP 5.4.45 version. Is it possible? is it simple? Thank you for your answer
Do you plan to build a new multi-server setup consisting of server servers, or should the whole setup be migrated to a single server?
With ISPConfig auto installer you can get additional PHP versions installed. There is PHP 5 also, but I believe not quite so old as PHP 5.4.45. I think it is PHP 5.6. So you can set PHP 5 for the websites that need it. I think you can not add Debian 7 host to your new ISPConfig multiserver setup because latest ISPConfig does not support Debian 7 anymore. Install the new setup with Debian 12 and auto installer, the use Migration Toolkit to copy the data from old to new.
