I've done this before successfully, but has something changed? I have an existing Server 2008 Standard with AD DC, and I am setting up a new Dell PowerEdge with Server 2012 Essentials R2 pre-installed. The setup isn't giving me a "Migration" option as I'm used to from 2012 and I believed 2012 R2.
This article https://technet.microsoft.com/en-us/library/dn281793.aspx#BKMK_ExistingAD
says "This option is only available if you deploy the Windows Server Essentials Experience role in Windows Server 2012 R2 Standard or Windows Server 2012 R2 Datacenter." which concerns me.
If that's the case, how would one setup a new 2012 R2 Essentials server in an existing 2008 AD environment (in which the 2008 server is to be demoted and removed eventually).
Thank you very much.
