ISPConfig is a controlpanel, this mean that it writes config files etc. It is not controllind any services, it writes just the configuration for these services.
Any ideas how long before 3.0.2?
In a few months. But you will have to remove your kind of replication in this ca
ase anyway as it conflicts with ispconfig.
Maybe you should leave your setup just as it is if it works for you and dont upadte ispconfig on the second server for now.
