Best method to move a 2k3 DC to physically different 2k8 server?
Posted on 2009-05-17
Current my network consists of two DC's (DC1 and DC2). DC1 is the DC with the GC. I want to move the entire AD from this server to a physically new 2k8 server. Which is the best/most reliable method in doing this?
Should I promote the 2k8 server to a DC with all roles, and then let replication copy all the data to the new server, and then demote the old DC1 server?
should I upgrade the 2k3 server to 2k8, make a backup, and move the entire backup over to the 2k8 box?
Obviously the second option is a longer process (and in my mind, more prone to data errors)
The reason I have not mentioned DC2 is because it is running purely as a backup, and it's primary function is actually
as an internal sharepoint server.
My network does have 2 sharepoint servers, Exchange 2k7, MsSQL 2k5 and 2k8 servers. I intend to add a 2k8 storage server and run a small SAN in the near future.
Also, a small side question: Is there a tool that will validate an AD for "best practices" ?
The reason I ask, is because I was not the one who setup this AD forest, and it seems to have some issues. For example: If I create a new user in AD, the user does not automatically get replicated to the exchange server. Any good resources/books/websites would be awesome information to have.
Any help/suggestions are MORE then welcome and apreciated,
