As we all know that the end-of-life date for PHP 7.4 was November 28, 2022 and PHP 7.4 and older versions are already obsolete, we recommend you to upgrade the PHP version on your servers as well.
The latest PHP 8.0 is not only the required minimum version for SocialEngine 6.4 and above, but also contains many security fixes and speed improvements.
If you are afraid to directly upgrade PHP and SocialEngine on your live site, then you can purchase our Setup Staging Environment & Examine Before Moving onto Live service. In this we will create a separate server on your AWS account and setup staging environment.
Once you are confident of your site on staging, you can purchase our Moving to Live from Staging Environment service.
