Installing Exchange 2010 in child domain

We have 800 users on exchange 2003:

root domain: abc.local
child domain: abc.domain.local

We have Exchange 2003 in the child domain only - abc.domain.local

We want to upgrade/transition to Exchange 2010 in same AD site and for only the child domain user mailboxes.

What setup / commands do we need to run (prepare ad / schema /legacypermissions etc) in each domain above. Please list step by step in correct order of execution.

thank you

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Akhater,

In the Prepare AD and Domains white paper on Technet, it mentions that the setup/PrepareSchema command must be run on a 64-bit computer. I have the same environment as jazmanuni but I do not have a 64 bit machine in my empty root.

Thoughts?

thanks : -)
