Upgrading from Exchange Enterprise 2000 to Exchange enterprise 2007, Windows 2000 domain
Posted on 2011-02-21
I know this has been asked and answered here many times, but my research has me greatly concerned that I could screw this up big time. Here is my scenario.
I have 2 Exchange 2000 Enterprise servers running on a Windows 2000 domain with 3 ADC's. I also have several Windows 2003 member servers, any of which could be promoted to an Windows 2003 ADC. I need a proven set up steps to get me to (as I understand it)
1. A Windows 2003 domain -via Domain prep and Forest prep
2. Then I think I need to do some sort of fix to prepare for Exchange 2007 (another domain and forest prep?)
3. Then I can promo an existing windows 2003 member server to an ADC and transfer all FMSO, PDC, etc.
4. Finally I can install Exchange Enterprise 2007 and start migrating users.
Of course the docs I read warn of dire consequences... Killing all the AD in the domain, etc.
I have imaged the Windows 2000 AD that I plan to install the domain and forest preps and I intend to remove it from the network during the domain and forest prep (good or bad idea?)
One of the Windows 2000 ADC is on another island, so screwing this up would be major.
Anyone with a good cook-book on this?
