Step 3: Migrate WSUS

Published: February 29, 2012

Updated: October 19, 2013

Applies To: Windows Server 2012, Windows Server 2012 R2



During the third step in the migration of your Windows Server Update Services (WSUS) server role, you will migrate binaries and security groups, back up the database, change the server identity, and apply security settings The following checklist describes the steps involved.

 

Task Description

3.1. Migrate WSUS update binaries

Move WSUS update binaries from the source server to the destination server.

3.2. Migrate WSUS security groups

Migrate local users and groups manually or by using Windows Server Migration Tools.

3.3. Back up the WSUS database

Use SQL Server Management Studio to back up and restore the WSUS database, computer groups, update approvals, and WSUS settings.

3.4. Change the WSUS server identity

Change the WSUS server identity on the destination server. Performing this step ensures that there is no effect on clients that are managed by WSUS during the migration process.

3.5. Apply security settings

Configure security settings on the new server. This includes configuring security settings on the destination server that you were using on the source server.

3.6. Review additional considerations

Review some additional actions that you should take after the migration is complete.

Use your preferred method to copy WSUS update binaries in the WSUS folder from the source server to the destination server (for example, Windows Server Migration Tools, Windows Explorer, Xcopy, or Robocopy). If you decide to use Windows Server Migration Tools to migrate WSUS update binaries to a destination server that is running Windows Server 2012, see Migrate WSUS Update Binaries from the Source Server to the Destination Server Using Windows Server Migration Tools.

ImportantImportant
Migrating WSUS update binaries is unnecessary if update files are stored on Microsoft Update.

You have the option of manually migrate only the WSUS Administrators and WSUS Reporters local security groups. Or, you can use Windows Server Migration Tools to migrate all local users and groups (including the WSUS Administrators and WSUS Reporters local security groups) from the source server to the destination server.

WarningWarning
The WSUS Server Migration Tools can be installed on the server using the Server Manager Add Features option.

Before you perform this procedure, verify that the destination server can resolve the names of domain users who are members of the local group during the import operation. If the source and destination servers are in different domains, the destination server must be able to contact a global catalog server for the forest in which the source domain user accounts are located. Use the following guidelines:

  • If the source server is a member of the domain and the destination server is a domain controller: Imported local users are elevated to domain users, and imported local groups become Domain Local groups on the destination server.

  • If the source server is a domain controller, and the destination server is not: Domain Local groups are migrated as local groups, and domain users are migrated as local users.

Use the following procedure to manually migrate users to the WSUS Administrators and WSUS Reporters local security groups.

  1. Right-click in the Taskbar, click Properties, highlight Toolbars, and then click Address.

  2. Type lusrmgr.msc, and then press ENTER.

  3. In the console tree of the Local Users and Groups MMC snap-in, double-click Users.

  4. Manually create a list of the local users.

  5. In the console tree of the Local Users and Groups MMC snap-in, double-click Groups.

  6. Manually add the users from the source server to the WSUS Administrators and WSUS Reporters groups.

Use the following procedure to use Windows Server Migration Tools to migrate users to the WSUS Administrators and WSUS Reporters local security groups.

  1. Open a Windows PowerShell session on the source server and on the destination server.

  2. Type the command below and press ENTER:

    Add-PSSnapin Microsoft.Windows.ServerManager.Migration

  3. In the Windows PowerShell session on the source server, type the following command to export local users and groups to a migration store:

    Export-SmigServerSetting -User <Enabled | Disabled | All> -Group -Path <MigrationStorePath> -Verbose

    MigrationStorePath represents the path of the location where you want to store migrated data. You can also use one of the following values with the -User parameter:

    • Enabled: Export only enabled local users

    • Disabled: Export only disabled local users

    • All: Export enabled and disabled local users

  4. Press ENTER.

    ImportantImportant
    You are prompted to provide a password to encrypt the migration store. Remember this password, because you must provide the same password to import data from the migration store on the destination server. If the path is not a shared location to which the destination server has access, you must copy the migration store to the destination server manually, or to a location that this destination server can access as it runs the Import-SmigServerSetting cmdlet.

  5. In the Windows PowerShell session on the destination server, type the following command to import local users and groups from the migration store that you created in Step 2:

    Import-SmigServerSetting -User <Enabled | Disabled | All> -Group -Path <MigrationStorePath> -Verbose

    MigrationStorePath represents the path of the location from which you want to import migrated data. You can also use one of the following values with the -User parameter:

    • Enabled: Export only enabled local users

    • Disabled: Export only disabled local users

    • All: Export enabled and disabled local users

  6. Press ENTER.

    WarningWarning
    After you enter the Import-SmigServerSetting cmdlet, you are prompted to provide the same password to decrypt the migration store that you created during the export process.

WSUS servers can be configured to use Windows Internal Database, the database software that is included with WSUS, or the full version of SQL Server. Regardless of which database option the source server is running, perform the following procedures to back up the WSUS database on the source server and restore the database to the destination server.

For an overview of backup and command-line syntax, see the following topics in SQL Server TechCenter:

For an overview of restore and command-line syntax, see the following topics in SQL Server TechCenter:

ImportantImportant
SQL Server Management Studio must be run with elevated administrator permissions throughout this procedure.

  1. After you connect to the appropriate instance of the database in Object Explorer, click the server name to expand the server tree.

    noteNote
    If the source server is using Windows Internal Database, the query changes depending on which version of WSUS you are currently running. For WSUS 3.2, the query is: \\.\pipe\mssql$microsoft##ssee\sql\query, and for WSUS on Windows Server 2012, the query is: \\.\pipe\Microsoft##WID\tsql\query.

  2. Expand Databases, and select the SUSDB database.

  3. Right-click the database, point to Tasks, and then click Back Up. The Back Up Database dialog box appears.

  4. In the Database list, verify the database name.

  5. In the Backup type list, select Full.

  6. Select Copy Only Backup. A copy-only backup is a SQL Server backup that is independent of the sequence of conventional SQL Server backups.

  7. For Backup component, click Database.

  8. Accept the default backup set name that is suggested in the Name text box, or enter a different name for the backup set.

  9. Optionally, in the Description text box, enter a description of the backup set.

  10. Specify when the backup set will expire and can be overwritten without explicitly skipping verification of the expiration data.

  11. Choose the backup destination by clicking Disk.

    ImportantImportant
    To remove a backup destination, select it and then click Remove. To view the contents of a backup destination, select it and then click Contents.

  12. In the Select a page pane, click Options to view or select the advanced options.

  13. On the Overwrite Media option, click one of the following:

    • Back up to the existing media set   For this option, click Append to the existing backup set or Overwrite all existing backup sets. Optionally:

      • Click Check media set name and backup set expiration to cause the backup operation to verify the date and time at which the media set and backup set expire.

      • Enter a name in the Media set name text box. If no name is specified, a media set with a blank name is created. If you specify a media set name, the media (tape or disk) is checked to see whether the name matches the name that you enter here.

    • Back up to a new media set, and erase all existing backup sets   For this option, enter a name in the New media set name text box, and, optionally, describe the media set in the New media set description text box.

  14. In the Reliability section, optionally select:

    • Verify backup when finished.

    • Perform checksum before writing to media.

    • Continue on checksum error.

  15. SQL Server 2008 Enterprise support backup compression. By default, whether a backup is compressed depends on the value of the Backup-compression default server configuration option. Regardless of the current server-level default, you can compress the backup or prevent compression at this time. To compress the backup, select Compress backup, or to prevent compression, select Do not compress backup.

  1. After you connect to the appropriate instance of the database in Object Explorer, click the server name to expand the server tree.

    ImportantImportant
    If the source server is using Windows Internal Database, the database name is: \\.\pipe\Microsoft##WID\tsql\query.

  2. Click New Query and copy the following SQL command to drop the WSUS database

    USE masterGOALTER DATABASE SUSDB SET SINGLE_USER WITH ROLLBACK IMMEDIATEGODROP DATABASE SUSDBGO

  3. Click Execute, to run the query

  4. Run the following query:

    RESTORE DATABASE [SUSDB] FROM DISK = N'C:\SUSDB.bak' WITH FILE = 1, MOVE N'SUSDB' TO N'c:\Windows\WID\Data\susdb.mdf', MOVE N'SUSDB_log' TO N'c:\Windows\WID\Data\SUSDB_log.ldf', NOUNLOAD, STATS = 10

    ImportantImportant
    Drive C: that is used in this example will vary according to the actual storage location for the files.

  5. In the Backup type list, select Full.

    WarningWarning
    Running the previous query will result in the following error message:

    Msg 3605, Level 16, State 1, Line 5Schema verification failed for database 'SUSDB'.Msg 3013, Level 16, State 1, Line 5RESTORE DATABASE is terminating abnormally

    Disregard the error message and continue.

  6. Open an elevated command prompt in Windows Server 2012, and run the following command:

    %programfiles%\update services\tools\wsusutil postinstall [sql parameter] [content parameter]

    ImportantImportant
    For WID, do not specify the SQL parameter.

  1. After you connect to the appropriate instance of the database in Object Explorer, click the server name to expand the server tree.

    ImportantImportant
    If the source server is using Windows Internal Database, the database name is \\.\pipe\Microsoft##WID\tsql\query.

  2. Click New Query and copy the following SQL command to drop the WSUS database (SUSDB):

    USE master

    GO

    ALTER DATABASE SUSDB SET SINGLE_USER WITH ROLLBACK IMMEDIATE

    GO

    DROP DATABASE SUSDB

    GO

  3. Click Execute to run the query.

  4. Run the following query:

    RESTORE DATABASE [SUSDB] FROM DISK = N'C:\SUSDB.bak' WITH FILE = 1, MOVE N'SUSDB' TO N'c:\Windows\WID\Data\susdb.mdf', MOVE N'SUSDB_log' TO N'c:\Windows\WID\Data\SUSDB_log.ldf', NOUNLOAD, STATS = 10

    ImportantImportant
    Drive C: that is mentioned in this example will vary according to the actual storage location for the files.

  5. This will result in the following error message:

    Msg 3605, Level 16, State 1, Line 5

    Schema verification failed for database 'SUSDB'.

    Msg 3013, Level 16, State 1, Line 5

    RESTORE DATABASE is terminating abnormally

    Disregard the error message and continue.

  6. Open an elevated command prompt in Windows Server 2012, and run the following command:

    %programfiles%\update services\tools\wsusutil postinstall [sql parameter] [content parameter]

    ImportantImportant
    For WID, do not specify the SQL parameter.

When a database is restored to a different server, it contains a set of users and permissions, although there may be no corresponding user log on information, or the log on information may not be associated with the same users. This condition is known as having "orphaned users." See article 168644 in the Microsoft Knowledge Base for instructions about how to resolve orphaned users.

After you restore a SQL Server 2005 database to SQL Server 2008, the database becomes available immediately, and it is then automatically upgraded.

The WSUS server identity on the destination server must be changed. Performing this step guarantees that WSUS-managed clients are not affected during the migration process. If the source server and the destination server run with the same identity, and a change is made to one of the servers, the communication between the client and server will fail.

  1. On the destination server, open a Windows PowerShell session with elevated user rights and run the following script:

    $updateServer = get-wsusserver

    $config = $updateServer.GetConfiguration()

    $config.ServerId = [System.Guid]::NewGuid()

    $config.Save()

  2. As soon as the server identity is changed, run the following command to generate a new encryption key:

    %ProgramFiles%\Update Services\Tools\wsusutil.exe postinstall

Refer to the settings that you recorded in the Migration Data Collection Worksheet, and then complete the following tasks to apply the security settings that you were using on the source server to the destination server.

  • SMTP server settings: If you are using an authenticating proxy or the email notification feature to an SMTP server that requires a password (or both), you must manually configure the proxy and email notification to the SMTP server, and enter the SMTP password on the new destination server if you are using email notification.

  • Code signing certificate: If you are using an advanced management tool that exposes local update publishing (such as Microsoft System Center Essentials 2007 or Microsoft System Center Configuration Manager 2007), copy the code-signing certificate.

To initialize a trust relationship between the update server and its clients, use the following procedures to point the downstream servers to the new WSUS server, and point the WSUS clients to the new WSUS server.

If you have downstream servers in your WSUS configuration, and if the server identity on the destination server was changed, perform the following procedure to point them to the new WSUS server.

  1. In the navigation pane of the downstream WSUS Server Administration console, click Options.

  2. Click Update Source and Proxy Server, and then click the Update Source tab.

  3. Select the Synchronize from another Windows Server Update Services server check box, and then type the server name and port number in the corresponding text boxes.

  4. Repeat step 1 through step 3 for additional downstream servers, if applicable. The synchronization can take several minutes to several hours to finish.

  5. To confirm that the downstream servers are synchronizing with the upstream server, in the WSUS Administration Console on the upstream WSUS server, click Downstream Servers. In the Status pane, confirm that the server’s Last Synchronization date is after the date that the previous steps were completed.

If the server identity on the destination server was changed, use the following procedure to point the WSUS clients to the new WSUS destination server.

  1. Open the Local Group Policy Editor, and in Specify intranet Microsoft update service policy, change the URL to reflect the new WSUS server.

  2. Update the Group Policy settings that are used to point WSUS clients to the WSUS server by entering the FQDN of the new WSUS server. After you have updated the Group Policy settings, WSUS clients will synchronize with the new WSUS server.

  3. To force the clients to detect the new destination server, open a command prompt, and run wuauclt.exe /resetauthorization /detectnow.

    noteNote
    To make sure that WSUS clients point to the new WSUS server immediately, you must force detection, which causes WSUS to update computer group membership. If you do not force a detection, it can take up to four hours for clients to point to the new WSUS server.

  4. Depending on the number of clients, the initial synchronization can take several minutes to several hours to finish. To confirm that the synchronization is complete, in the WSUS Administration Console, expand Computers, and then click All Computers. In the Status pane, click Any, and then click Refresh. Confirm that the computers that you expect to see synchronizing to this WSUS server are listed. The Last Contact Date has to be refreshed with a post-migration time stamp.

    TipTip
    To force a report that the Last Contact Date was updated, run wuauclt.exe /resetauthorization /detectnow, and then run wuauclt.exe /reportnow.

  5. After the clients have synchronized, confirm that clients are installing approved updates based on your WSUS configuration settings. In the WSUS Administration Console, click Reports, and then click Computer Tabular Status. Select the Report Options that are applicable to the clients, and then click Run Report.

  6. To make sure that no WSUS clients are still pointing at the old WSUS server, wait a week and then open the WSUS Administration Console on the old WSUS server. Expand Computers, and then click All Computers. In the Status pane, click Any, and then click Refresh. Sort on Last Status Report. There should be no clients that have a Last Status Report date after the date that the synchronization completed.

After the migration is complete, consider the following:

  • It is important to have a backup plan for restoring the WSUS server role if there is a migration failure. You do not need to roll back the migration on the source server because the migration process makes no changes to it. You do not need to roll back the migration on the destination server because it is a new server.

  • After you have confirmed that no WSUS clients are contacting the old WSUS server, you can uninstall WSUS from the source server. To perform this operation, see the section titled Retire the WSUS role on the source server (optional) in the Windows Server Update Services 3.0 SP2 Migration Guide topic: Post-migration Tasks for WSUS.
