I wonder if I could have some feedback from some people that did the migration from php to PHP-FPM. The issue I have is that I have lots of scripts on the service. Some written by customers and I cant modify them all.
The reason I want to migrate to PHP-FPM is not particular about speed, but more because I was told that with PHP-FPM I can run 2 instances of PHP. So I am planing to run PHP5-FPM and PHP7-FPM and than slowly move and test the scripts on PHP7. But old scripts can still run on PHP5.
So this brings me to my 2 questions. 1. I run at the moment php56w 5.6.40-1.w6 package from Webtatic on a CentOS 6.10 server. When I install php5-fpm, do I have to make changes to all the scripts to work with the FPM version of PHP5? 2. Do you see any major complication to run 2 PHP-FPM instances on one server?
Thank you all for the feedback, this is a important decision for me and for me the dual install would be the perfect solution if I do not open the Pandora box by doing this.
Best wishes, Thomas
