Quote - In other words, it is not possible to export my DAZ Victoria 3 character and all the other related stuff into Poser 5?

Afraid not.  You will just have to dig out your original DAZ .exe files and re-install them
into your Poser runtime.  (Hopefully you saved them somewhere.)
And if you have created specific characters in DAZ Sudio,
you will have to attempt to re-create them in Poser.
