Can I consolidate three Domain Controllers in three different forest having three different DNS namespace into one new domain controller that will have a different name dns namespace ???

Thanks Mkline71, as you said it easier said that done. I'm creating a testing environment where I can try that before procceding my migration. has any one of you guys done it before ? also, what kind of problems faced you during migration ?

Please let me know.

this is all part of my research.

Thank you all for your help.

I forgot to mention that I have 2 Exchange servers too. and I need to migrate them to exchange 2k10

it is pretty complicated structure.

Thanks,

It's easy enough if you test things out properly. The user account and group migration stages can be tested without disrupting users (with the right settings).

It's pretty much inevitable that some machines will fail to move over cleanly, make sure you know how to deal with that and the user profiles manually.

Exchange isn't too bad, ultimately you'll be exporting mailboxes and importing them. That can be a single step, or a multi-step process. Chances are it'll be better to handle that from the Exchange 2010 side. Which versions of Exchange are you coming from?

Hi chris,

My exchange versions are 2003 and 2007, the new one will be 2010
