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

After all batches have been migrated, perform a final global group remigration to ensure that any late changes that are made to global group membership in the source domain are reflected in the target domain.

You can remigrate global groups by using the Active Directory Migration Tool (ADMT)snap-in, the ADMT command-line option, or a script.

To remigrate global groups 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. Use the Group Account Migration Wizard by performing the steps in the following table.

    Wizard page Action

    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.

    Group Selection

    Click Select groups from domain, and then click Next. On the Group Selection page, click Add to select the groups in the source domain that you want to migrate, click OK, and then click Next.

    Or

    Click Read objects from an include file, and then click Next. Type the location of the include file, and then click Next.

    Organizational Unit Selection

    Type the name of the organizational unit (OU), or click Browse.

    In the Browse for Container dialog box, find the container in the target domain that you want to move the global groups into, and then click OK.

    Group Options

    Select the Update user rights check box.

    Ensure that the Copy group members check box is not selected.

    Ensure that the Update previously migrated objects check box is not selected.

    Select the Fix membership of group check box.

    Select the Migrate Group SIDs to target domain check box.

    User Account

    Type the user name, password, and domain of an account that has administrative rights in the source domain.

    Object Property Exclusion

    Clear the Exclude specific object properties from migration check box.

    Conflict Management

    Select the Migrate and merge conflicting objects (all other options are cleared) check box.

  3. When the wizard has finished running, click View Log, and review the migration log for any errors.

  4. Open Active Directory Users and Computers, and locate the target OU. Verify that the global groups exist in the target domain OU.

To remigrate global groups 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 Group command with the appropriate parameters, and then press ENTER:

    ADMT GROUP /N "<group_name1>" "<group_name2>" /SD:" <source_domain>" /TD:" <target domain>" /TO:" <target OU>" /MSS:YES /CO:REPLACE

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

    ADMT GROUP /N "<group_name1>" "<group_name2>" /O: "<option_file>.txt"

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

    Parameters Command-line syntax Option file syntax

    <Source domain>

    /SD:"source_domain"

    SourceDomain="source_domain"

    <Source OU> location

    /SO:"source_OU"

    SourceOU="source_OU"

    <Target domain>

    /TD:"target_domain"

    TargetDomain="target_domain"

    <Target OU> location

    /TO:"target_OU"

    TargetOU="target_OU"

    Migrate GG SIDs

    /MSS:YES

    MigrateSIDs=YES

    Conflict management

    /CO:REPLACE

    ConflictOptions=REPLACE

  3. Review the results that appear on the screen for any errors.

  4. Open Active Directory Users and Computers, and locate the target OU. Verify that the global groups exist in the target domain OU.

To remigrate global groups by using a script

  • Prepare a script that incorporates ADMT commands and options for migrating global groups by using the following sample script. Copy the script to Notepad, and save the file with a .wsf file name extension in the same folder as the AdmtConstants.vbs file.

    <Job id=" RemigratingGlobalGroupsBetweenForests" >
<Script language="VBScript"  src="AdmtConstants.vbs" />
<Script language="VBScript" >
   Option Explicit

   Dim objMigration
   Dim objGroupMigration

   '
   'Create instance of ADMT migration objects.
   '

   Set objMigration = CreateObject("ADMT.Migration" )
   Set objGroupMigration = objMigration.CreateGroupMigration

   '
   'Specify general migration options.
   '

   objMigration.SourceDomain = "source domain" 
   objMigration.SourceOu = "source container" 
   objMigration.TargetDomain = "target domain" 
   objMigration.TargetOu = "target container" 
   objMigration.ConflictOptions = admtReplaceConflicting

   '
   'Specify group migration specific options.
   '

   objGroupMigration.MigrateSIDs = True

   '
   'Migrate specified group objects.
   '

   objGroupMigration.Migrate admtData, Array("group name1" ,"group name2" )

   Set objGroupMigration = Nothing
   Set objMigration = Nothing
</Script>
</Job>
