thread1674-1529099 I found this thread but I did not see any closure. I am doing the same thing: intstalling two 2008 R2 standard servers to be the DC with AD (the second for redundancy). I don't want to touch the clients if possible. I know how to join the server to the existing domain. What I am looking for is detailed guidance (step by step) on how to complete the migration. Is there any written document to do this? Thanks.
