NPS Server Migration: Migrating the NPS Server

  • Artikel

 

Applies To: Windows Server 2012

This topic contains steps and procedures for migrating the Network Policy Server (NPS) role service from a legacy source server to a new x64-based destination server running Windows Server 2012.

This topic includes sample Windows PowerShell cmdlets that you can use to automate some of the procedures described. For more information, see Using Cmdlets.

Known issues

If you previously created conditional attributes for your remote access policy using Called Station ID and Calling Station ID, the comparison of these attributes in Windows Server 2012 now uses a regular expression instead of matching the exact string. For a description of these attributes, see Remote Access Policy Conditions in the IAS Authorization section.

Exporting settings from the source server

Use the following procedures to export the NPS settings from your x86-based or x64-based source server prior to migrating to an x64-based server running Windows Server 2012. Follow the steps in the appropriate section based on the version of Windows Server that is running on the source server:

Warning

When you use the following procedures to export configuration settings, apply appropriate precautions when moving these files from the source server to destination servers. NPS server configurations are not encrypted in the exported XML file, and contain shared secrets for RADIUS clients and members of remote RADIUS server groups. Therefore, sending these files over a network connection might pose a security risk. You can add the file to an encrypted, password protected archive file before moving the file to provide greater security. In addition, store the file in a secure location to prevent access by unauthorized users.

Exporting settings from Windows Server 2003

Configuration settings for Internet Authentication Service (IAS) in Windows Server 2003 are stored in .MDB files. Configuration settings for Network Policy Server (NPS) in Windows Server 2012 are stored in .XML files. Iasmigreader.exe is a command-line tool that exports the configuration settings of IAS on a computer running Windows Server 2003 to a text file. You can obtain the iasmigreader.exe command line migration tool for migrating Windows Server 2003 IAS settings to Windows Server 2012 from the following locations:

  1. Windows Server 2012 installation media provides a copy of the migration tool in the \sources\dlmanifests\microsoft-windows-iasserver-migplugin\ directory.

  2. The migration tool is available in the %windir%\syswow64\ directory on a server running Windows Server 2012.

To export settings from a source server running Windows Server 2003

  1. Copy iasmigreader.exe to the source server into a directory configured in the %path% environment variable.

    Tip

    To review the source server’s %path% configuration, type echo %path% at a command prompt and press Enter.

  2. At an elevated command prompt, type iasmigreader.exe, and then press Enter. The migration tool will automatically export settings to a text file.

    Important

    Configuration changes made to IAS will take at least one minute to be available for export.

  3. IAS settings are stored in the file ias.txt located in the %windir%\system32\ias directory on the source server. If you are running a 64-bit version of Windows Server 2003, the ias.txt file is located in the %windir%\syswow64\ias directory.

  4. You must manually copy SQL log configuration settings on the source server to a file (example: sql.txt).

    To record these settings:

    1. At an elevated command prompt, type ias.msc, and then press Enter.

    2. In the IAS console tree, click Remote Access Logging, right-click SQL Server, and then click Properties.

    3. Record the configuration settings on the Settings tab, and then click Configure.

    4. Manually record all configuration settings from the Connection and Advanced tabs by copying them into the sql.txt file. Alternatively, you can click the All tab and enter Name and Value settings displayed on each line into the sql.txt file. For a list of text logging and SQL configuration settings that you need to record manually, see NPS Server Migration: Appendix A - Data Collection Worksheet.

  5. Copy the ias.txt and sql.txt files to the migration store file location.

Warning

Store the ias.txt and sql.txt files in a secure location. These files contain shared secret information and SQL connection strings.

Important

When you migrate the configuration settings of the IAS role service that is running on a 32-bit or a 64-bit Windows Server 2003–based source server to the NPS role service that is running on a Windows Server 2012–based destination server, the import procedure seems to complete successfully. However, the Extensible Authentication Protocol (EAP) method is misconfigured. This occurs because the migration tool generates a faulty parameter that is stored in the configuration text file (ias.txt). For more information about this issue and for a workaround, see The EAP method is configured incorrectly during the migration process from Windows Server 2003 32-bit or a 64-bit to Windows Server 2008 R2 (https://go.microsoft.com/fwlink/?LinkID=181982).

Exporting settings from Windows Server 2008

Configuration settings for NPS in Windows Server 2008 are stored in .XML files that can be directly imported to the destination server. The Network Shell (NetSh) command line utility can be used to export and import these settings. You can also use the Windows interface to import and export these settings.

Warning

You cannot use the Windows interface or a command line to export or import detailed SQL configuration settings. For a list of text logging and SQL configuration settings that you need to record manually, see NPS Server Migration: Appendix A - Data Collection Worksheet.

Importing settings to the destination server

Use the following procedures to import the NPS settings from your x86-based or x64-based source server to an x64-based destination server running Windows Server 2012.

Importing settings from Windows Server 2003

The configuration file ias.txt that was exported from the source server is in a format that can be imported to a destination server running Windows Server 2012. If SQL accounting settings were saved, these settings are recorded manually in the sql.txt file.

Important

When you migrate the configuration settings of the IAS role service that is running on a 32-bit or a 64-bit Windows Server 2003–based source server to the NPS role service that is running on a Windows Server 2012–based destination server, the import procedure seems to complete successfully. However, the Extensible Authentication Protocol (EAP) method is misconfigured. This occurs because the migration tool generates a faulty parameter that is stored in the configuration text file (ias.txt). For more information about this issue and for a workaround, see The EAP method is configured incorrectly during the migration process from Windows Server 2003 32-bit or a 64-bit to Windows Server 2008 R2 (https://go.microsoft.com/fwlink/?LinkID=181982).

To import settings from a source server running Windows Server 2003

  1. Copy the configuration file ias.txt that was exported to the migration store file location to the destination NPS server. Alternatively you can import configuration settings directly from the migration store file location by supplying the appropriate path to the file in the import command.

  2. On the destination server, use either netsh or Windows PowerShell to import the configuration.

    • To use netsh, do the following:

      1. Open an elevated command prompt, type the following command and then press Enter:

        netsh nps import filename="path\ias.txt"

        Replace path with the directory where the ias.txt file is located. Verify that a message appears indicating that the import process was successful.

        Tip

        If the configuration file is located on a network share, provide full path to the file. For example: netsh nps import filename = “\fileserver1\Data\ias.txt”.

    • To use Windows PowerShell, do the following:

      1. On the Start screen, type PowerShell, and then click Enter.

      2. Switch to the NPS context, enter the following Windows PowerShell command:

        Import-Module NPS

      3. To import the configuration, enter the following:

        Import-NpsConfiguration [-Path] <String>

        Replace String with the directory where the ias.txt file is located. Verify that a message appears indicating that the import process was successful.

        Tip

        For example: Import-NpsConfiguration –Path c:\temp\ias.txt

  3. If required, configure SQL accounting. To configure SQL accounting:
