We have an independent Windows 2008 domain with about 1800 user / computers. We started with windowsNT, migrated it to Windows 2000 then to 2003 and are now on 2008. We are now asked to become a part of the company domain / forest which is being established. This will perhaps require a change in my domain name too. As our windows domain computer have been a part for domain for very long a lot of things like mail clients and other application clients are tied up with the domain user profile. In such a state if the parent domain changes what will be the effect on these? i do not hv a choice of making my domain a trusted domain of new company domain.
Pl suggest what action plan I should have to have a seamless transfer?
