Are there any considerations to address when attempting to upgrade a 2008 domain controller?
- About 2 years ago I migrated our DC's to 2016. It went very well. If you have DNS scavenging rules, some of them are server specific. You will need to set them on one of the new servers. The biggest things are upgrading replication and testing.

The recommended way to upgrade a domain is to promote domain controllers that run newer versions of Windows Server & demote older DCs as needed. Details here: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/upgrade-domain-controllers- Also be aware that you will need to change your file replication type from FRS to DFSR, if you haven’t already, before adding a 2022 DC.
