Domain migration to new Domain

Hello,

we are sitting on a active directory domain abc.com, externally we are 123.abc.com.  Our new corp purchased abc.com now and wants to migrate us to it ASAP.. but its currently messing up internal access to websites, redirects, etc....

I would like to migrate the abc.com to something new, 123.xyz.com.   Is there any tools that I should look at, we are about 500 users with 75 servers.

thanks for the push!.

Its look like you need to rename the domain. If  you are using windows 2003 and above versions where you can rename domain name.Refer the below link

Note : Domain rename is not possible in Windows 2000 server

Or if you want to create server as Domain controller then you need to transfer FSMO roles to achieve this
