Hi all experts,
We have an environment with a Domain contoso.local with 2 DC’s and 1 Subdomain schools.contoso.local with 2 DC’s and 5 RODC’s. Domainlevel is 2008R2.
We want to raise the domain to 2012 r2 without update the RODC’s, only the main DC’s on contoso.local and schools.contoso.local should be 2012 R2.
What would be the correct way to achieve this?
According to Microsoft we only have to “adprep” and “domainprep” on the 4 main DC’s. rodcprep is not necessary on those 4 main DC’s or is it? Also do we have to do something on the RODC’s as well?
Thank you for your replies
