Hello all,
Just doing some planning for our first 2012 DC for our forest/domain.
We've decided to achieve the upgrade by doing the following:
1. Demote and remove one DC in our Root Domain
2. Demote and remove one DC in our Child Domain
3. Rebuild both servers as Windows 2012
4. Promote one DC into the Forest Domain - Thereby performing the ADPrep /ForestPrep and /Domain Prep
5. promote one DC into the Child Domain - Thereby performing the ADPrep /Domain Prep
6. Run ADPrep /DomainPrep /GPPrep manually in both the Root and Child Domains
Can anyone see anything fundamentally wrong with this procedure? I've been using http://msmvps.com/blogs/mweber/archive/2012/07/27/upgrading-an-active-directory-domain-from-windows-server-2008-or-windows-server-2008-r2-to-windows-server-2012.aspx as a guide to this. It suggests using an Enterprise Admin account to promote the DC in the Forest Domain, I presume the same account will be fine to promote into the Child Domain as well?
Any other "gotchas" I should be aware of?
