The first few chapters of this book were focused on understanding AD DS and its capabilities. This chapter is different from those as it is more focused on the implementation of AD DS. In the first part of this chapter, we learned about the implementation of domain controllers in different scenarios. The second part of this chapter was focused on AD DS migration from an older version of AD DS to AD DS 2016. Here, we learned how to plan AD migration properly. As part of this learning experience, we looked at how to perform Active Directory health checks, application audits, information gathering, and AD design reviews. Last but not least, we learned how to migrate from AD DS 2012 R2 to AD DS 2016.

In the next chapter, we are going to learn about managing Active Directory objects.
