You can use the domain rename process to change the names of your domains, and you can also use it to change the structure of the domain trees in your forest.
There are some applications incompatible with domain rename, but are not limited to:
Microsoft Exchange Server 2000, 2007, 2010
Microsoft Internet Security and Acceleration (ISA) Server
Microsoft Live Communications Server 2005
Microsoft Office Communications Server 2007 or above
Microsoft SharePoint Portal Server 2003
Microsoft Systems management Server (SMS) 2003
Microsoft Operations Manager 2005
Prerequisites
1. The forest functional level has been raised to Windows Server 2003 or above
2. Create the necessary shortcut trust relationships (if required)
3. Install the support tools in all domain controllers
4. You must use the Enterprise Domain Administrator to perform domain rename
5. Backup all domain controllers in the forest (include child-domains and other Tree root domains)
6. Domain rename must be run on a control station which is a member server in the domain
