An Active Directory migration can be complex. You must first understand your source environment at both the domain and the object level to make good decisions and minimize the data you must migrate.

Some migration scenarios add even more complexity. This white paper details the major challenges of Active Directory migrations, including complex migration scenarios, and explains how the right migration tools help speed your migration and ensure its success.
