Dear, due our ISPConfig network (master-slave setup) is going to be pretty huge, and most of the services have some serious customization from the standard, we have trouble when we are going to upgrade because when we do "Reconfigure services" we lost all of them, and we need to take back manually. Question is: while we update the ISPConfig if we don't do "Reconfigure services" we'll facing some problems? Or every services will going to works as before? Let us know. Thank you.
