About this tag
Functional level in Active Directory determines which Windows Server operating system features are available in a domain or forest. Discussions on WindowsForum.com cover upgrading domain controllers from older functional levels, such as Windows 2003 or 2008 R2, to newer versions like Windows Server 2016. Users seek guidance on replacing outdated domain controllers with minimal disruption and address compatibility concerns when multiple domains with trusts are involved. Potential issues, such as smart card failures after raising the functional level, are also noted. The tag focuses on practical steps and troubleshooting for raising functional levels in enterprise environments.
