We have three domain controllers. &nbsp;The original is running Windows 2008 r2. &nbsp;The other two were added later and are running Windows 2019. &nbsp; All three are setup with global catalog and we only have one domain. &nbsp; We now want to decommission the older Windows 2008 server. &nbsp; Is it as simple as deleting it via active directory or do we need to run DCPROMO on the older server?
