    Has any 1 considered just creating a new Perfect server for Debian 9 from scratch and making that new server a "mirror" of the original Debian 8 server?

    I mean most upgrades leave stuff broken or miss-configured. Just think of the force move from PHP5 -> PHP7. Why not skip the hassle by simply making a new mirror server and using unison to sync /var/vmail and /var/www.

    Is it possible to change the "master" ISPconfig server after and remove the old one?
