1. How to validate Windows Server 2016 and Server 2008 servers

There are numerous concepts and tasks to perform when you manage a domain, regardless of the size of the organization, and that is why Microsoft has integrated a wide range of features, roles and services within its business operating system (Windows Server). Each one focused on facilitating the life of the administrator and is not for less, any error or bad configuration can trigger a complete cascade of adverse situations, not only for the person who manages the server, but also for all client computers linked to the domain ..

Speaking of domains, there is a fundamental element when we talk about Windows Server and it is the domain controller (DC-Domain Controller) which has the very delicate task of allowing users and computers access to domain resources by previously validating Your credentials Remember that if a user can access the domain freely without the appropriate permissions we are violating multiple security variables that can cause headaches, so the domain controller will help avoid that situation since as such the domain controller authenticates users and teams so they can join the respective domain.

Nowadays, many companies make use of Windows Server 2008 R2 as their base server where the domain controller is logically but a measure of security and scalability at the level of functions is to be able to migrate said domain controller to Windows Server 2016 which It is a more stable version and with better performance both at the level of roles and performance, in addition to this, migration avoids having to configure everything again since migrating will transfer all roles, FSMO parameters and other changes that the controller has of domain of origin..

TechnoWikis will explain through this tutorial how to migrate a domain controller from Windows Server 2008 R2 to Windows Server 2016 in a functional and safe way, but without complications.
