forest function level

About this tag
The forest function level determines the minimum Windows Server version required for domain controllers in an Active Directory forest. In a Windows Server 2022 to 2019 domain join scenario, the forest function level must be compatible. If the forest function level is set to Windows Server 2019 or lower, a Windows Server 2022 domain controller can join the domain. However, issues may arise if the forest function level is not raised appropriately or if there are schema or replication problems. Common troubleshooting steps include verifying the current forest function level, ensuring all domain controllers are updated, and checking for any domain preparation requirements for the newer server version.
