Without wishing to repeat a question thats probably been asked here before but I can't seem to find an immediate and satisfying answer.
I am seriously considering purchasing Carrara Pro from DAZ3d and taking up their 65% discount offer, I know absolutely nothing about this software. I can buy this for either the MAC or PC  whichever is the most appropriate and possibly the best platform.
My purpose is to use Carrara as a substitue for Poser 7 to do posing and renders. Poser is driving me nuts what with its crashes and freezes and slow performance even on a dual core PC.

I want to use the sets and props etc. that I have aquired from DAZ, V3, V4 etc. and from Rosity and other places.
I have a large library of hair peices and clothing and many light sets and shader products so I am obviously nervous of doing this.
What I need to know before I jump into the deep end is will there be serious problems using  existing Poser software packages with Carrara Pro and getting them to install and work as they do in Poser 7? Or will they work fine? Also could  I use existing Poser scenes that I have already made?
Any advice would be greatfully appreciated.
