I just have a simple question but never thought about it, when I install BT 4 prefinal on my system, can I easily update to the final version using APT (since BT4 is Debian based) or will there be any problems? Or is there any other way to update the complete system to the final version without reinstalling it on hdd?

And is there already any VMWare Image of the BT4 prefinal? Just found one of the beta

Thanks in Advance

so long
