We are a large school system with 51 schools and each school is its own seperate domain with its own DC but all are in one forest. We want to go to one unified 2008 R2 DC. Does anyone have any recent documentation on how to move from multiple DC's in one forest to one DC in one forest?

Hey Matt,

We looked at doing a similiar migration in our school district. We ended up setting up a large domain and slowly bringing machines into the domain. We would pick 1/3 of the schools during the summer that were either getting new computers or were close to schools getting new comptuers and wipe them clean. Then join them to the domain.

A couple of questions:

What is the bandwidth like between schools? How is the network - mesh? Start? Buslike?

Do you have standard computers - ex: certain dell models?

Do you have standard software/image?

Just for personal knowledge, where are you located? We are down here in Georgia.

to consolidate from 51 to 1 domain means a major migration project.  You can use a tool like ADMT to migrate

Now if you just wanted to add a 2008 R2 DC to each domain that is easy.  

Thanks

Mike

Granular recovery for Microsoft Exchange

With Veeam Explorer for Microsoft Exchange you can choose the Exchange Servers and restore points you’re interested in, and Veeam Explorer will present the contents of those mailbox stores for browsing, searching and exporting.

We are also in Ga.

A couple of questions:
What is the bandwidth like between schools?  We have 50 megs guaranteed burstable to 100 megs
How is the network? Star
Do you have standard computers - ex: certain dell models? We have several Dell models at the moment being used throughout the system.
Do you have standard software/image? We are trying to get to all Win 7 computers but yes we typically work of a specific image.
Just for personal knowledge, where are you located? We are down here in Georgia.

Thank you for your response

mkline71: thanks for the response.

Each one of the 51 school DC's is server 2003. With going to one domain we want to just get our AD structure in order and not so messed up. I have looked at other articels suggesting using the ADMT as well.

Where at in GA? Must be Atlanta area because I can't think of any district with 51 schools.

Because you have a decent connection, you may want to put just RODCs and BranchCache servers at each of the sites (if money permits).

The biggest piece of advice I can give is get a single basic image (just Windows 7) and deploy your software. It will save you so much time as you convert schools.

Great city. I drive through it on my way to Helen sometimes. If you have any other questions, feel free to email me at Jmoody@glynn.k12.ga.us. We went through this same situation so I may be of a little use.
