Create New Domain Tree or New Forest?

We are getting ready to change the name of our company and I am trying to prepare for the change.  We currently have one domain, yyy.com,  which is at the Windows 2003 functional level.  We also have one Exchange 2003 server that services all of the users in the yyy.com domain.

I need to create a new domain zzz.com in preparation for the name change.  I'll be using a W2K8 Server as a domain controller, leaving it at the 2003 functional level.  The trust between the yyy.com and zzz.com will be two-way transitive. I envision that eventually the yyy.com domain will go away.

Is it better to create another domain tree in the existing forest or create a new domain in a new forest?  I've read that both are possible in this scenario. What happens if/when I need to delete the yyy.com domain since it is the Forest root domain (I believe)?

 I do not need to create a new administrative boundary as I will be administering both domains.  It is imperative that the existing Exchange server be able to handle email for both domains.

Your experience and expertise in this matter is greatly appreciated.

If you're going to migrate over to zzz.com then demote yyy.com you have to migrate to a new forest. You can't demote the forest root domain.

That sounds good to me.  Will the Exchange server be able to service email from both domains (i.e. user logs in to either domain during transisition)? If so, I'll go with your answer.

Thanks.

I'm not much into Exchange, but a quick search regarding one Exchange org. between two forests:

If it will make you would feel better you should ask a moderator to add your question also to the Exchange zone. I'm sure a more qualified Exchange expert might have something to add.

But your forest root must remain, so you need a new forest :)

A second option since you're on Exchange 2003 is a domain rename of your existing domain.
