It is possible allready to use ISPConfig 3 to manage more than one server? I'm going to install an new server as dom0 and would like to know if ISPConfig 3 is able to mange diffenrent domU? What about the databas from ISPConfig 2, can it be used in ISPConfig 3?
The multi server functionality has not been tested extensively and the installer is not able yet to do automatic multy server installs. ISPConfig 3 should not be used on production systems yet. No.
Would it be posible to upgrade ISPConfig 2 to 3 in the future oder to use the database? What is your goal to cope with ISPConfig 3?
No. We will build a import script for ISPConfig 2 data later. Please see the different threads here in the forum about ISPConfig 3, I posted the goals and specifications several times.
