Specifies how Active Directory Migration Tool handles the group migration. These options are defined as follows:
Update user rights
Copies the user rights assigned in the source domain to the target domain.
Copy group members
Copies the members of the groups you selected to migrate. This option allows you to maintain the group membership information in the target domain. This option is not available in the Group Merging and Mapping Wizard.
Update previously migrated objects
Updates the members of the groups you selected to migrate, even if those members were previously migrated. This option is available only if the Copy group members check box is selected. This option is not available in the Group Merging and Mapping Wizard.
Migrate group SIDs to target domain
Adds the security ID (SID) of the migrated user accounts and groups in the source domain to the SID History of the new user accounts and groups in the target domain. This feature uses a secure connection to the source domain controller. For more information about SID History, see Understanding security.
Do not rename accounts
Tries to assign the migrated group the same name as the group in the source domain. If a naming conflict occurs, the options specified on the Naming Conflicts page control how the migrated group is named.
Rename with prefix
Adds the specified prefix to the name of each migrated group in the target domain. The original group with the same name in the target domain remains unchanged.
Rename with suffix
Adds the specified suffix to the name of each migrated group in the target domain. The original group with the same name in the target domain remains unchanged.
