That is correct from 8.3 we start using network objects instead of names.
So here is my recomendation:
1- Go to 8.2 first and build the names and then upgrade to 8.3 so the names will be translated automatically to an object newtork
2-Start the object network configuration from 8.3 manually , then you just add them to the ACL's and nat stuff.
