IP Configuration: Post-migration Tasks

Article
07/02/2012

Applies To: Windows Server 2008 R2

After you have migrated IP configuration settings and data as directed in IP Configuration: Migrating IP Configuration Data, verify the migration and, if necessary, roll back IP configuration migration by using the procedure in this section.

Verifying the migration

Perform the following steps to verify your IP configuration migration.

To verify the IP configuration migration

Open a Command Prompt window on the destination server. To do this, click Start, click Run, type cmd, and then press Enter.
Verify that all IP configurations that you wanted to migrate exist on the correct network adapters on the destination server. To do this, type the following, , and then press Enter.
```
IPConfig -all
```
Compare the results of the IPConfig -all command with the IPConfig output you generated on the source server in the procedure “To export IP configuration settings from the source server” in IP Configuration: Migrating IP Configuration Data.
For static IP address migration, verify that you can access the destination server by using the same IP address as the source server had before the migration. You can verify this by using the ping command in a Windows Command Prompt session.

Rolling back migration

If necessary, perform the following steps to roll back IP configuration migration.

To roll back migration

If you obtained a different static IP address for your source server, and migrated the statically-configured IP address to the destination server, either disconnect the destination server from the network or obtain a new static IP address for the destination server.
Set the IP address of the source server back to the pre-migration static IP address.
Connect the source server back to the network if you disconnected it in step 1.

Troubleshooting cmdlet-based migration

The Windows Server Migration Tools deployment log file is located at %windir%\Logs\SmigDeploy.log. Additional Windows Server Migration Tools log files are created at the following locations.

%windir%\Logs\ServerMigration.log
On Windows Server 2008 and Windows Server 2008 R2: %localappdata%\SvrMig\Log
On Windows Server 2003: %userprofile%\Local Settings\Application Data\SvrMig\Log

If migration log files cannot be created in the preceding locations, ServerMigration.log and SmigDeploy.log are created in %temp%, and other logs are created in %windir%\System32.

If a migration cmdlet fails, and the Windows PowerShell session closes unexpectedly with an access violation error message, look for a message similar to the following example in the %localappdata%\SvrMig\Logs\setuperr.log file.

FatalError [0x090001] PANTHR Exception (code 0xC0000005: ACCESS_VIOLATION) occurred at 0x000007FEEDE9E050 in C:\Windows\system32\migwiz\unbcl.dll (+000000000008E050).  Minidump attached (317793 bytes).

This failure occurs when the server cannot contact domain controllers that are associated with domain users or groups who are members of local groups, or who have rights to files or shares that are being migrated. When this happens, each domain user or group is displayed in the GUI as an unresolved security identifier (SID). An example of a SID is S-1-5-21-1579938362-1064596589-3161144252-1006.

To prevent this problem, verify that required domain controllers or global catalog servers are running, and that network connectivity allows communication between both source and destination servers and required domain controllers or global catalog servers. Then, run the cmdlets again.

If connections between either the source or destination servers and the domain controllers or global catalog servers cannot be restored, do the following.

Before you run Export-SmigServerSetting, Import-SmigServerSetting or Get-SmigServerFeature again, remove all unresolved domain users or groups who are members of local groups from the server on which you are running the cmdlet.
Before you run Send-SmigServerData or Receive-SmigServerData again, remove all unresolved domain users or groups who have user rights to files, folders, or shares on the migration source server.

Viewing the content of Windows Server Migration Tools result objects

All Windows Server Migration Tools cmdlets return results as objects. You can save result objects and query them for more information about settings and data that were migrated. You can also use result objects as input for other Windows PowerShell commands and scripts.

Result object descriptions

The Windows Server Migration Tools Import-SmigServerSetting and Export-SmigServerSetting cmdlets return results in a list of MigrationResult objects. Each MigrationResult object contains information about the data or setting that the cmdlet processes, the result of the operation, and any related error or warning messages. The following table describes the properties of a MigrationResult object.

Property name	Type	Definition
ItemType	Enum	The type of item being migrated. Values include General, WindowsFeatureInstallation, WindowsFeature, and OSSetting.
ID	String	The ID of the migrated item. Examples of values include Local User, Local Group, and DHCP.
Success	Boolean	The value True is displayed if migration was successful; otherwise, False is displayed.
DetailsList	List <MigrationResultDetails>	A list of MigrationResultDetails objects.

Send-SmigServerData and Receive-SmigServerData cmdlets return results in a list of MigrationDataResult objects. Each MigrationDataResult object contains information about the data or share that the cmdlet processes, the result of the operation, any error or warning messages, and other related information. The following table describes the properties of a MigrationDataResult object.

Property name	Type	Definition
ItemType	Enum	The type of migrated item. Values include File, Folder, Share, and Encrypted File.
SourceLocation	String	The source location of the item, shown as a path name.
DestinationLocation	String	The destination location of the item, shown as a path name.
Success	Boolean	The value True is displayed if migration was successful; otherwise, False is displayed.
Size	Integer	The item size, in bytes.
ErrorDetails	List <MigrationResultDetails>	A list of MigrationResultDetails objects.
Error	Enum	Errors enumeration for errors that occurred.
WarningMessageList	List <String>	A list of warning messages.

The following table describes the properties of objects within the MigrationResultDetails object that are common to both MigrationResult and MigrationDataResult objects.

Property name	Type	Definition
FeatureId	String	The name of the migration setting that is related to the item. Examples of values include IPConfig and DNS. This property is empty for data migration.
Messages	List <String>	A list of detailed event messages.
DetailCode	Integer	The error or warning code associated with each event message.
Severity	Enum	The severity of an event, if events occurred. Examples of values include Information, Error, and Warning.
Title	String	Title of the result object. Examples of values include NIC physical address for IP configuration, or user name for local user migration.

Examples

The following examples show how to store the list of the result objects in a variable, and after migration is complete, use the variable in a query to return the content of result objects.

To store a list of result objects as a variable for queries

To run a cmdlet and save the result in variable, type a command in the following format, and then press Enter.
```
$VariableName = $(Cmdlet)
```
The following is an example.
```
$ImportResult = $(Import-SmigServerSetting -FeatureId DHCP -User all -Group -Path D:\rmt\DemoStore -force -Verbose)
```
This command runs the Import-SmigServerSetting cmdlet with several parameters specified, and then saves result objects in the variable ImportResult.
After the Import-SmigServerSetting cmdlet has completed its operations, return the information contained in the result object by typing a command in the following format, and then pressing Enter.
```
$VariableName
```
In the following example, the variable is named ImportResult.
```
$ImportResult
```
This command returns information contained in the result objects that were returned by Import-SmigServerSetting in the example shown in step 1. The following is an example of the output that is displayed by calling the ImportResult variable.
```
           ItemType  ID                              Success  DetailsList
           --------  --                              -------  -----------
          OSSetting  Local User                         True  {Local User, Loc...
          OSSetting  Local Group                        True  {Local Group, Lo...
     WindowsFeature  DHCP                               True  {}
```
Each line of the preceding sample is a migration result for an item that was migrated by using the Import-SmigServerSetting cmdlet. The column heading names are properties of MigrationResult objects. You can incorporate these properties into another command to return greater detail about result objects, as shown by examples in step 3 and forward.
To display a specific property for all result objects in the list, type a command in the following format, and then press Enter.
```
$<VariableName>| Select-Object -ExpandProperty <PropertyName>
```
The following is an example.
```
$importResult | Select-Object -ExpandProperty DetailsList
```
You can run more advanced queries to analyze result objects by using Windows PowerShell cmdlets. The following are examples.
- The following command returns only those details of result objects that have the ID Local User.
```
$ImportResult | Where-Object { $_.ID -eq "Local User" } | Select-Object -ExpandProperty DetailsList
```
- The following command returns only those details of result objects with an ID of Local User that have a message severity equal to Warning.
```
$ImportResult | Where-Object { $_.ID -eq "Local User" } | Select-Object -ExpandProperty DetailsList | ForEach-Object { if ($_.Severity -eq "Warning") {$_} }
```
- The following command returns only the details of result objects with an ID of Local Group that also have the title Remote Desktop Users.
```
$ImportResult | Where-Object { $_.ID -eq "Local Group" } | Select-Object -ExpandProperty DetailsList | ForEach-Object { if ($_.Title -eq "Remote DesktopUsers") {$_} }
```
