we are in the process of renaming the company name and subsequently we want to change the windows 2000 domain name and the Exchange 2000 server organization to reflect our new name.
Now, I know that there are many issues involved in changing the domain. I read almost everything in the Internet and I came out with different ideas.
I don't know if my ideas are correct, so I am here to ask for the help of you expert...
Requirements: we want to keep both names for the time being, so customers can gradually get used to the new name. We don't want to forward the mail directed to the old domain to our new domain. Users must be able to access both their old and newly created mailboxes. The win2k domain is behind a firewall. The Users in the new domain have to keep the rights they had in the old domain.
1) My first idea is to set up a domain controller and a mail server backup all the users' accounts and the mailboxes, take it off the network and demote the other domain controllers in order to start a new domain. I am aware that doing that I have to get rif also of the exchange organization. After that, I rejoin the server I took off the network and create trust relationship between the two domains for the time being until we decide to get rid completely of the old name.
2) create a new domain in a new box with the new name and create trust relationship between the two domains for the time being until we decide to get rid of the old name.
3) Set up a domain controller and a mail server backup all the users' accounts and the mailboxes, update the other domain controllers to win2k3, uninstall Exchange, change the name, reinstall exchange, create the trust. Keep the two domains for the time being.
I look forward to receive your suggestions,
