I know it's a little early, but I also know there are people out there who could probably answer this question.

In my current infrastructure I've got an NS that's performing my CMS duties and a 2nd NS that is performing my Helpdesk and Asset Management duties. The only interaction the two have is a daily inventory forwarding job from my CMS NS to my Helpdesk & Asset NS. 

Will I still be able to forward inventory data from my CMS NS if I upgrade it to NS7?  I don't need any of the new hierarchy stuff, just inventory data.  I know Connector will probably be able to work as a stopgap if i have to, but that seems like it could be really messy.
