This section will help you to set the permissions that are required by Migration Manager for Active Directory.
Migration Manager for Active Directory requires administrative access to each source and target domain involved in Active Directory migration.
We recommend that you to create a new user account for the migration activities in each source and target domain instead of using an existing one.
To grant the account administrative access to the Active Directory domain, add the account to the domain’s local Administrators group as follows:
If you have established two-way trusts between each source and target domain or forest trust, you can grant this single account administrative access to each source and target domain. This powerful account must be maintained closely and should be deleted after the project is complete. It is recommended that this account be owned by one individual and one backup individual (or as few individuals as possible).
