exchange, active directory

I have 6 AD sites in US which are having child relationship with our site which is headquartered at NY

The sites have their own exchange server and DC in their site
All these sites have exchange 2007 servers.

They all have child relationship with our site.
And having netbios name as for ex. For Indiana it is ind.domain.lan

We have main site in NY which is domain.lan

We are promoting our exchange server 2007 to exchange 2013 in primary site in NY.

In this regard we want to collapse their child relationship we want all these sites to have netbios name as domain.lan which we have

We want them to have forest-forest relationship

So how can we do this

Options

Do we need to build separate dc’s in their site and make netbios name same as domain.lan and do replication

or something else is required?

Hi

Promoting the exchange part is making the question unclear, Lets focus on the domain first.

You now have domain.lan as HQ domain and 6 subdomains as branchoffice domains.
Here you have setup trust relations of Some kind i think?!

Now you want to stretch the main lan to your 6 branchoffices right? and exchange would be centralised in HQ as is AD, policies etc etc

If this is the case, Yes you should rollout new DCs which are member of the HQ domain, this can be full blown DCs or RODC depends your need. They can also be DNS and GC as well.
These new DCs in the new forest should get Some trust relation with the old domain and then the fun can begin by migrating users and their email to the new domain.

Cool challenge!
