I am going to upgrade all the site php version to 7.1. Already have some sites up and running with the compiled php 7.1 fpm. My plan is: 1) Backup /etc/apache2/sites-available/ 2) Update the mysql db "web_domain.fastcgi_php_version" to php 7.1 3) Run resync -> websites to regenerate the config But as I remember the resync -> websites is very slow (update config file and reload apache for each site). Is it possible to just rewrite the conf with the new setting and then restart the apache once? Thanks.
