I've just purchased the migration tool. I want to migrate from a multiserver setup to a single/multiserver setup. Old servers server 1: web&db master server with ISPConfig 18.104.22.168p9 interface server 2: mail server server 3: dns1 server server 4: dns2 server mirror of dns1 New servers server 1: web, db, mail, file master server with ISPConfig 3.1dev interface server 2: dns1 server server 3: dns2 server mirror of dns1 In the README it only says to copy the migration tool to the SOURCE (the server with the data). So to which server should I copy? Only the master or on every server from the old setup and run the tool on every old server? Need to backup all my data before I run the tool. So I haven't tryed it yet. Do the old servers need to know the new ones by hostname ( need to add them to vi /etc/hosts) or are private/internal IPs enough?
