Active Directory migrations
Directory services form the backbone of the IT infrastructure for nearly every organisation.
Microsoft Active Directory (AD) is the most widely adopted directory platform, and there are many strategic and operational reasons why organisations may choose to undertake an AD migration:
There are a variety of reasons why businesses undergo the process of AD migrations, they include:

Starting over
Sometimes called clean slate or greenfield migrations, these are a practical choice when Active Directory has undergone so many upgrades and changes that it’s no longer fit for purpose.

Divestitures
When part of an organisation is sold off or divested, this element of the business needs to be migrated out of the current Active Directory.

Mergers and acquisitions
Mergers and acquisitions often lead to a period of coexistence before the new organisations settle on a centralised IT policy. The new policy may involve a fresh start (called a greenfield AD) or the combination of multiple users and computers into the most appropriate AD.
Whatever the driving force behind your own AD migration, the process can be complex, time-consuming, and fraught with challenges – not least if your users are working remotely from multiple locations.
