Is the old DC running on frs or dfsr replication?<br />
You will probably have better luck making sure you are up to dfsr replication first. You most likely will have to raise the domain and forest levels too.<br />
It MIGHT work without doing the above, but with a single DC, the risk is too great to break things.

I knew Microsoft would drop FSR support as it was extremely problematic in earlier 2016 versions.

<div class="content wysiwyg-content">
I have only one DC. That DC is running 2008 R2. The domain and forest functional levels are both set at Windows 2003.<br />
<br />
I am building a new DC to retire the old. That new DC will be running Server 2019. <br />
<br />
Do I have to first raise the domain and forest functional levels to 2008 R2 on the current DC before I add the 2019 server to the domain? Do I then promote the 2019 server to a DC after first raising the levels to 2008 R2?<br />
<br />
<br />
Thank you

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter.
