Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2

Applies to: Active Directory Migration Tool 3.2 (ADMT 3.2)

Remigrating user accounts and workstations in batches helps you track the migration process. For each batch of users, first translate local user profiles, and then migrate workstations. Verify that the profile and workstation migration succeeded, and then migrate the user accounts. Remigrate global groups after each batch. For more information, see Remigrating All Global Groups After All Batches Are Migrated, later in this guide.

Translating local user profiles

The Active Directory Migration Tool (ADMT) translates profiles for supported computer migration objects. For a list of which operating systems are supported for computer migration objects for different versions of ADMT, see Active Directory Migration Tool versions and supported environments.

User profiles are stored locally on the workstation. When a user logs on to another workstation, he or she must create a new, unique local user profile. Translate the local user profiles for the first batch of users immediately after migrating all user accounts.

Local profiles are translated in replace mode because if you perform the profile translation in add mode, certain aspects of software installation that use Group Policy software deployment might not work. Any application that is packaged with Windows Installer version 2.0 (which is included on workstations running Windows 2000 Server Service Pack 3 (SP3) or Service Pack 4 (SP4) and Windows XP Service Pack 1 (SP1) or Service Pack 2 (SP2), as well as in many common software packages) might not function after the profile is translated. For example, the application executable files might not be removed after the last user removed the application. When the ADMT Security Translation Wizard is translating local profiles in replace mode, it reverts to add mode if a profile is locked. This might result in a successful profile translation. However, application installations might not function after the profile is translated.

Note

The night before you notify the users to log on by using their new accounts in the target domain, translate the local user profiles. Translating profiles the night before ensures that the new user profile reflects the most current user settings.

You can translate local user profiles by using the ADMT snap-in, the ADMT command-line option, or a script.

To translate local user profiles by using the ADMT snap-in

  1. For each workstation in the source domain that you migrate, add the ADMT resource migration account to the local Administrators group.

  2. On the computer in the target domain on which ADMT is installed, log on by using the ADMT account migration account.

  3. Use the Security Translation Wizard by performing the steps in the following table.

    Wizard page Action

    Security Translation Options

    Click Previously migrated objects.

    Domain Selection

    Under Source, in the Domain drop-down list, type or select the NetBIOS or Domain Name System (DNS) name of the source domain. In the Domain controller drop-down list, type or select the name of the domain controller, or select Any domain controller.

    Under Target, in the Domain drop-down list, type or select the NetBIOS or DNS name of the target domain. In the Domain controller drop-down list, type or select the name of the domain controller, or select Any domain controller, and then click Next.

    Translate Objects

    Click User Profiles.

    Security Translation Options

    Click Replace.

    ADMT Agent Dialog

    Select Run pre-check and agent operation, and then click Start.

  4. Review the results that are displayed on the screen for any errors. After the wizard completes, click View Migration Log to see the list of computers, completion status, and the path to the log file for each computer. If an error is reported for a computer, you will have to refer to the log file on that computer to review any problems with local groups. The log file for each computer is named MigrationTaskID.log and is stored in the Windows\ADMT\Logs\Agents folder.

To translate local user profiles by using the ADMT command-line option

  1. On the computer in the target domain on which ADMT is installed, log on by using the ADMT account migration account.

  2. At the command line, type the ADMT Security command with the appropriate parameters, and then press ENTER.

    ADMT SECURITY /N "<computer_name1>" "<computer_name2>" /SD:" <source_domain>" /TD:" <target_domain>" /TO:" <target_OU>" /TOT:Replace /TUP:YES

    As an alternative, you can include parameters in an option file that is specified at the command line as follows:

    ADMT SECURITY /N "<computer_name1>" "<computer_name2>" /O "<option_file>.txt"

    The following table lists the common parameters that are used for migrating user accounts, along with the command-line parameter and option file equivalents.

    Parameters Command-line syntax Option file syntax

Migrating workstations in batches

After you migrate a batch of local user profiles, migrate the corresponding batch of user workstations. When you migrate a workstation between domains, the Security Accounts Manager (SAM) database is migrated along with the computer. Accounts in the local SAM database (such as local groups) that are used to enable access to resources always move with the computer. Therefore, these accounts do not have to be migrated.

If a workstation has managed service accounts installed and those accounts have been previously migrated, ADMT provides an option to reinstall the migrated managed service account on the migrated computer and update Service Control Manager. So that ADMT can perform this operation, the account performing the computer migration needs permissions to modify the security descriptor of the migrated managed service account.

Note

Use a low value for the RestartDelay parameter to restart workstations immediately after joining them to the target domain, or as soon as possible thereafter. Resources that are not restarted after migration are in an indeterminate state.

You can migrate workstations and member servers by using the AMDT snap-in, ADMT command-line option, or a script.

To migrate workstations by using the ADMT snap-in

  1. On the computer in the target domain on which you installed ADMT, log on by using the ADMT resource migration account.

Remigrating user accounts in batches

After you have verified the success of local user profile and user workstation migration for the user batch, migrate the user accounts for that batch. You can migrate user accounts in batches by using the ADMT snap-in, the ADMT command-line option, or a script.

You can migrate user accounts by using the ADMT snap-in, by using the ADMT command-line option, or by using a script. If you are migrating user accounts that have authentication mechanism assurance enabled, use an include file. In the include file, specify the original user principal names (UPNs) from the source domain as the target UPNs to keep the authentication mechanism assurance working. For more information about using an include file, see Use an Include File.

Important

When you start a user migration with their security identifier (SID) history from the command line or from a script, you must perform the migration on a domain controller in the target domain. It is recommended that you use a full version of SQL Server when you install ADMT on a domain controller.

To migrate the current batch of user accounts by using the ADMT snap-in

  1. On the computer in the target domain on which ADMT is installed, log on by using the ADMT account migration account.

  2. Complete the User Account Migration Wizard by performing the steps in the following table.

Remigrating all global groups after user account migration

A large user account migration might take place over an extended period of time. For this reason, you might have to remigrate global groups from the source to the target domain after you migrate each batch of users, to reflect changes made to the membership of groups in the source domain after the initial global group migration occurred. For more information about, and procedures, for remigrating global groups, see Remigrating All Global Groups After All Batches Are Migrated, later in this guide.
