ers reboot into the new domain with the designated settings migrated.

Migrating Other Domain Functionality

In addition to the Group, User, and Computer Migration Wizards, several other wizards

can be used to migrate specific domain-critical components. These wizards operate using

the same principles as those described in the preceding sections and are straightforward in

their operation. The following is a list of the additional wizards included in ADMT v3.1:

. Security Translation Wizard

. Reporting Wizard

. Service Account Migration Wizard

. Exchange 5.5 Mailbox Translation Wizard

. Retry Task Wizard

. Password Migration Wizard

Virtually all necessary functionality that needs replacing when migrating from one

domain to another can be transferred by using ADMT v3.1. It has proven to be a valuable

tool that gives administrators an additional option to consider when migrating and

restructuring Active Directory environments.

Migrating Server Roles to Windows Server 2008 R2

Migrating server roles, system settings, and data from your 32-bit and older Windows

operating systems to Windows Server 2008 R2 has been made easier with the introduction

516

CHAPTER 16

Migrating from Windows Server 2003/2008 to Windows Server

2008 R2

of the Windows Server Migration Tools, the Printer Migration Wizard, and the

printbrm.exe command-line utility. The following sections go over the installation, setup,

and usage of these tools.

Windows Server Migration Tools

The Windows Server Migration Tools are a Windows Server 2008 R2 feature, installed via

the Add Feature Wizard, that uses PowerShell cmdlets to facilitate the migration of server

roles, system settings, and data from older versions of Windows and 32-bit versions of

Windows to Windows Server 2008 R2. Before the Windows Server Migration Tools can be

used to migrate services from one server to another, the tools need to be installed on both

the source and destination servers. Because the Windows Server Migration Tools are

included with Windows Server 2008 R2, the tool must be packaged and installed on

Windows Server 2003 or Windows Server 2008 systems if the source servers are running

either of these operating systems.

Windows Server Migration Tools source server requirements are as follows:

. Windows Server 2003 SP2 or later

. 25MB of free space to store the Windows Server Migration Tools folder

. Microsoft .NET Framework 2.0

ptg

. Windows PowerShell 1.0 or later

As with any migration, a backup of the system or data being migrated is recommended

prior to using the Windows Server Migration Tools. Prior to decommissioning any

migrated server, confirm the new server is functioning properly.

To prepare the target Windows Server 2008 R2 server for migration, perform the following

steps:

1. On the target server, go to Add Features, click Windows Server Migration Tools, and

then click Next.

2. Click Install and then click Close when installation is complete.

3. On the target server, open a command prompt as an administrator.

4. Type CD %windir%\system32\servermigrationtools, and then press Enter.

5. Type smigdeploy /package /architecture x86 /os ws03 /path .

NOTE

If the source server is 64-bit, change x86 to amd64, and if the source server is

Windows Server 2008, change WS03 to WS08. The previous command will create an

appropriately named folder in the path specified.

To prepare the source server for migration, perform the following steps:

1. Copy \SMT_WS03_x86 from the target server to the source server.

2. Open a command prompt, type cd \SMT_WS03_x86, and then press Enter.

3. Type .\smigdeploy.exe, and then press Enter.

You have now installed the Windows Server Migration Tools and are ready to start migrating.

Migrating AD and DNS

An Active Directory Domain Services and DNS migration to Windows Server 2008 R2 can

be accomplished quickly and easily. In the following example, we migrate AD Domain

Services and DNS from a legacy domain controller to a Windows Server 2008 R2 system.

These procedures assume the Windows Server 2008 R2 system is a member server and that

you have used adprep.exe to prepare both the forest and domain. If this is not the case,

follow the steps earlier in this chapter before continuing on.

To migrate AD and DNS:

1. On the destination server, click Start, click Run, type DCPROMO, and then click OK.

2. On the Welcome page, check Use Advanced Mode Installation, and then click Next.

3. On the Operating System Compatibility page, click Next.

4. Click Existing Forest, confirm that the Add a Domain Controller to an Existing

ptg

Domain option is selected, and then click Next.

16

5. Type the domain name, and set the administrative credentials that will be used to

perform the installation if you are not already logged on as a domain admin.

6. Select or confirm the correct domain, and then click Next.

7. Select or confirm the correct site, and then click Next.

8. If the source server is a DNS server and a global catalog, leave DNS Server and Global

Catalog checked. If it is not a DNS server or a global catalog, uncheck the corre-

sponding role(s).

9. If prompted regarding delegation for this DNS server cannot be found, click Yes.

10. On the Install from Media page, click Next.

11. Select Use This Specific Domain Controller, select the source domain controller, and

then click Next.

12. Change or accept the default location for the system folders, and click Next.

13. Provide your Directory Service Restore mode administrator password, and click Next.

14. Review the summary and click Next.

15. Click Finish and restart the domain controller when complete.

16. On the source server, open a command prompt and type dnscmd /enumdirectory-

partitions. Note the partitions, as we will be using them on the target server in

the next step.

17. On the target server, open a command prompt and type dnscmd /enumdirectory-

partitions to confirm the same directory partitions exist and are enlisted.

Migrating from Windows Server 2003/2008 to Windows Server

2008 R2

18. If either or both partitions are not listed, type dnscmd /enlistdirectorypartition

, for example, dnscmd /enlistdirectorypar-

tition DomainDNSZones.companyabc.com.

19. On the source server, type net stop “dns server”.

20. Export the following Registry keys:

HKLM\System\CurrentControlSet\Services\DNS\Parameters and

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\DNS Server.

21. From a command prompt, type xcopy %windir%\system32\dns C:\export /s.

22. If C:\export does not exist, type d when prompted to create the directory.

23. Delete the Samples folder that was just copied to C:\export as it’s not needed.

24. From a command prompt, type net start “dns server”.

25. On the target server, type Net stop “dns server”. Copy both exported Registry

keys to the target server, and then double-click them both to complete the import.

26. Copy the content of C:\Export from the source server to %windir%\system32\dns.

27. Type net start “dns server”.

NOTE

ptg

At this point, both domain controllers are online and servicing client authentication and

DNS requests. If the source domain controller is holding any FSMO roles, follow the

steps earlier in this chapter to move them to another DC.

NOTE

The next steps, which include migrating the IP configuration, can be done manually or

be done using the Windows Server Migration Tools. The process for installing and con-

figuring the tools on both servers is described in detail previously in this chapter.

28. On the source server, click Start, Administrative Tools, Windows Server Migration

Tools, right-click Windows Server Migration Tools, and click Run as Administrator.

29. Type Export-smigserversetting –ipconfig –path C:\export -verbose.

30. Provide a password when prompted.

31. Type ipconfig /all > C:\export\sourceIP.txt.

32. Copy the export file and sourceip.txt to your destination server.

33. Change the source server’s IP address to a different static IP.

34. On the destination server, click Start, Administrative Tools, Windows Server

Migration Tools, right-click Windows Server Migration Tools, and click Run As

Administrator.

35. Type import-smigserversetting –ipconfig ALL -sourcephysicaladdress

” -targetphysicaladdress

” -path -verbose.

Multiple Domain Consolidation Migration

519

NOTE

This example assumes one network adapter on the source domain controller. For multi-

ple NICs, add a source and target physical address reference for each. This process is

described in more detail later in the chapter.

NOTE

Use sourceip.txt to get the physical address information from the source server

and use ipconfig /all in a separate command prompt to get it from the destina-

tion server.

36. Provide the password set during export when prompted.

37. Rename the source DC using the following command: netdom renamecomputer

%computername% /newname:.

38. Rename the target DC using the same command, but change the to that

of the source DC’s old name.

39. Restart to complete the migration.

Migrating DHCP

DHCP server migration to Windows Server 2008 R2 can be accomplished quickly and

easily using the Windows Server Migration Tools. In the following example, we use the

Windows Server 2008 R2 Migration Tools to migrate DHCP server settings from a 32-bit

Windows Server 2003 SP2 server. The following steps assume you have already followed

the procedures for installing the Windows Server Migration Tools and have configured

both source and target servers. The overall process of using the Windows Server Migration

Tools to migrate DHCP services is as follows:

1. Verify the DHCP configuration on the source server is current and working correctly.

2. Click Start, Administrative Tools, Windows Server Migration Tools, right-click

Windows Server Migration Tools, and click Run As Administrator.

3. Type stop-service dhcpserver, and press Enter.

4. Type get-smigserverfeature, and press Enter.

NOTE

Get-SmigServerFeature is the command that scans the source computer for roles or

features supported for migration using the Windows Server Migration Tools.

5. Type export-smigserversetting -featureid dhcp –ipconfig –user ALL -group

-path -verbose.

CHAPTER 16

Migrating from Windows Server 2003/2008 to Windows Server

2008 R2

NOTE

The –user and –group switches are optional and only used when migrating the DHCP

Administrators group membership. The –user switch is only used if there are local user

accounts listed as members.

6. Type a password when prompted, and press Enter to start the export.

7. After the export completes, move the export created in to the target

server.

8. Unauthorize the source DHCP server.

9. On the target server, click Start, Administrative Tools, Windows Server Migration Tools.

10. Type import-smigserversetting –featureid dhcp –path -verbose.

11. Type the password used to create the migration file earlier.

NOTE

The Windows Server Migration Tools installs the required roles and features to com-

plete the migration. In this case, the DHCP server role has been installed.

ptg

12. Confirm Success is marked as True to confirm migration is complete.

13. Type start-service dhcpserver.

14. Authorize the new DHCP server to complete the server migration.

Migrating IP Configuration

The Windows Server Migration Tools can be used to migrate the IP configuration from

your source Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2

server to your target Windows Server 2008 R2 system. The IP configuration migration can

be included in any other service migration by simply adding the –ipconfig switch to the

export-smigserversetting command.

The overall process of using the Windows Server Migration Tools to migrate DHCP services

is as follows:

1. On the source server, click Start, Administrative Tools, Windows Server Migration

Tools, right-click Windows Server Migration Tools, and click Run As Administrator.

2. Type Export-smigserversetting –ipconfig –path -verbose.

3. Provide a password when prompted.

4. When the export is complete, you can copy the export file to your destination server

and then start the import process.

NOTE

Take a snapshot of your current IPConfig by typing ipconfig /all >

C:\ipconfig.txt. This can be used to verify settings postmigration if needed.
