Hello,

Two domains, the root, domain.com, and a son, hijo.domain.com
I have Exchange 2003 on domain.com, domain.com with accounts only for email. Windows users belong to the child domain and have different accounts.

That is, each user has two accounts, one for windows and another one for email, so you have to enter username and password each time you open Outlook.

I'm going to migrate to Exchange 2010, but I want the users have mailboxes hijo.domain.com instead of domain.com

How do I have to do the migration?
1. Prepare domain of domain.com
2. Prepare domain of hijo.domain.com
3. Installing Exchange 2010 in domain.com
4 ?????

Thanks and regards
