A user object (User1) in your AD DS forest has these attributes: whenCreated, distinguishedName, objectGUID, and objectSID. After migrating User1 to the fabrikam.com forest with ADMT, which attributes will change?

When migrating a user object between Active Directory forests using ADMT, the distinguishedName will always change because the user's location within the directory structure (domain, organizational unit) is different in the new forest. The objectSID will also change because SIDs are unique identifiers within a forest and cannot be duplicated. ADMT creates a new object in the target forest, assigning it a new SID. The whenCreated attribute, which records the creation time of the original object, remains unchanged during an ADMT migration as it's typically preserved. The objectGUID is a globally unique identifier and is also preserved during an ADMT migration to maintain object uniqueness across forests, especially for linked mailboxes or resource access.
