No, this wont work. there is no upgrade because ispconfig 2 and 3 use totally different system architectures and different software. This means that you will have to format the server harddisk and then do a complete reinstall as described in the ispconfig 3 setup guides.
ISPConfig 3 is not intended and was not made as a update for ispconfig 2. ISPConfig 3 is a new multi server control panel for virtual users etc. whil ispconfig 2 is a single server control panel for system users. Both versions will be developed and updated independantly in future.
