TLDR: Is it possible to run Roundcube 1.5.6 in a RHEL 9 environment without any problems?
Hello everyone,
we are currently using Roundcube version 1.5.4 in a RHEL 8 environment with PHP version "7.4.33".
Specifically, this is PHP "7.4.33-1.module+el8.8.0+17865+ef7eddfa".
The exact RHEL release is "Red Hat Enterprise Linux release 8.8 (Ootpa)".
We want to update to Roundcube 1.5.6 LTS at most for the time being, because we do not know whether we will be missing essential functionality if we update to Roundcube "1.6.6".
Now the question: If we first update Roundcube to version 1.5.6, is it then possible to update the operating system from RHEL 8 to RHEL 9 without any problems?
I mean, does the PHP version that comes with RHEL 9 by default harmonize with Roundcube 1.5.6 LTS?
As far as I know, RHEL 9 offers PHP version 8.0.
Has anyone had any experience with such a constellation?
If the PHP version is problematic under RHEL 9, should we install a more suitable PHP version then?
Or is it better to bite the bullet and upgrade to Roundcube 1.6.6 instead?
Answers would make me very happy
