Do i need to install ispconfig 2 before i install ispconfig 3?

Hi

Im sorry for my last post my vps provider response immediately according to my question which virtualization do i used, the first reply is OpenVZ and second one is

"actually it is Virtuozzo - which is similar to OpenVZ; however, not opensource - we use the commercial/enterprise version which is Virtuozzo"


that is the last response of my provider...


can you give advice on how can i managed my vps with ispconfig3 properly
i subscribed unmanaged vps that's why i need opensource control panel

Thanks a lot for the help...
