The Active Directory directory service can be compared to a phone book or a personal organizer. In it we can organize days, weeks, months and even years, recording people's names, birthdays, important data and much more. The directory service has exactly the same meaning, that of organizing and, above all, having a centralized place to search for the information we need in our day-to-day work. The main task to be carried out in this project is to migrate from one domain to another in order to bring them together to form part of the same forest of a single domain. With the implementation of this solution, it is hoped that the respective AD Forests and Domains will be consolidated in order to take better advantage of the benefits that a consolidated AD environment brings to organizations, such as centralized management of network resources in an agile and more secure manner.
