Freshly install Windows Server 2019 Essentials on new hardware.Prepare Windows Server 2012 R2 Essentials (existing AD DC).According to the documentation, there should be a 21-day waiting period, but the documentation applies again to older versions and not to 2019 - so I don't know exactly whether I can even switch both servers online at the same time.Īccording to the (outdated) documentation, I would now proceed as follows: Also, there is the "Essentials" restriction that only one Essentials server is allowed per network. T he source server has other roles in addition to Active Directory, such as DNS, DHCP, and NPS. I want to make sure I don't miss any step.

The in-place upgrade is described, but not how to migrate to Windows Server 2019 Essentials on new hardware. The documentation does not provide instructions for this scenario. We have a Windows Server 2012 R2 Essentials and would like to migrate to Windows Server 2019 Essentials.
