To address these requirements, we need to go beyond legacy access management. Cybercrimes are skyrocketing and identity protection is at stake. Most software vendors are moving into SaaS model. The majority of the workforce is still working from home and accessing sensitive corporate data via unsecured networks. Businesses are using more and more cloud services now. However, the modern access management requirements are complicated. For more than 21 years, AD DS helps organizations to manage digital identities. The maximum forest and domain functional level we can choose still is Windows Server 2016.Īctive Directory Domain Services was first introduced to the world with Windows Server 2000. But with Windows Server 2019 there were NO new forest or domain functional levels. With each and every Windows Server release up to Windows Server 2016, had a new forest and domain functional level. There was a big difference with Windows Server 2019 when it comes to forest and domain functional levels. We need to upgrade it manually once older domain controllers are decommissioned. Upgrading the operating system or adding domain controllers that run Windows Server 2022 to an existing AD infrastructure isn't going to upgrade the forest and domain functional levels automatically. AD migrations from other operating systems (newer than Windows Server 2008R2) also follow a similar process.ĪD DS' improvements are bond to its forest and domain functional levels. Microsoft released Windows Server 2022 recently (Aug 2021) and I thought it good to demonstrate how we can migrate AD from 2008 R2 to the newest. In the past, I did a similar blog post covering migration AD from Windows Server 2008 to Windows Server 2016. Even business does not have a business requirement to upgrade, end of life operating system leaves no choice but to upgrade. End-of-life operating systems have a direct impact on various industry compliances, IT audits, Penetration tests, and so on. Because of this many organizations wanted to migrate away from these legacy operating systems. Windows Server 2008 and Windows Server 2008 R2 Operating system reached the end of their support cycle on the 14th of January 2020.
