I'm currently running PHP 5.6 with the CGI handler for PHP-FPM. I'm also running suexec. I may have some sites that are not compatible with PHP 7.2 by the end of the year, so I want to make sure I have all sites isolated from one another as much as possible. Would it make sense to switch to mod_ruid2? If so, are there any caveats to switching from PHP 5.6 using CGI to PHP 7.2 using DSO?
