will updating the packages keep the configurations?

[soheil.server]

I have customized the configurations of the apache, mysql and php on my server.
1. will updating these packages in directadmin panel keep the configurations? or I have to set the configurations again?
2. what about restarting each of them? for example if I run `systemctl restart httpd`, will its configurations be reset?
thanks

1. update will destroy any custom changes, you must place this in the custom folder
2. restarting wont effect the configurations
