User State Migration Tool (USMT) logs can be used to monitor the migration and to troubleshoot errors and failed migrations. This article describes the available command-line options to enable USMT logs. It also describes new XML elements that can be used to configure:

Which types of errors are fatal and should halt the migration.
Which types are non-fatal and should be skipped so that the migration can continue.

Log command-line options

The following table describes each command-line option related to logs, and it provides the log name and a description of what type of information each log contains.

Command line Option	File Name	Description
/l"[Path]FileName	`ScanState.exe.log` or `LoadState.log`	Specifies the path and file name of the ScanState log or LoadState log.
/progress:[Path]FileName	Specifies the path and file name of the Progress log.	Provides information about the status of the migration, by percentage complete.
/v:[VerbosityLevel]	Not applicable	See Monitoring options in ScanState syntax.
/listfiles:[Path]FileName	Specifies the path and file name of the Listfiles log.	Provides a list of the files that were migrated.
Set the environment variable MIG_ENABLE_DIAG to a path to an XML file.	`USMTDiag.xml`	The diagnostic log contains detailed system environment information, user environment information, and information about the migration units (migunits) being gathered and their contents.

Note

The log files can't be stored in StorePath. If the log files are stored in StorePath, the log files are overwritten when USMT runs.

ScanState and LoadState logs

ScanState and LoadState logs are text files that are created when the ScanState and LoadState tools run. These logs can be used to help monitor the migration. The content of the log depends on the command-line options that are used and the verbosity level that is specified. For more information about verbosity levels, see Monitoring options in ScanState syntax.

Progress log

A progress log can be created using the /progress option. External tools, such as Microsoft System Center Operations Manager, can parse the progress log to update the monitoring systems. The first three fields in each line are fixed as follows:

Date: Date, in the format of day shortNameOfTheMonth year. For example: 08 Jun 2023.
Local time: Time, in the format of hrs:minutes:seconds (using a 24-hour clock). For example: 13:49:13.
Migration time: Duration of time that USMT was run, in the format of hrs:minutes:seconds. For example: 00:00:20.

The remaining fields are key/value pairs as indicated in the following table.

Key	Value
program	`ScanState.exe` or `LoadState.exe`.
productVersion	The full product version number of USMT.
computerName	The name of the source or destination computer on which USMT was run.
commandLine	The full command used to run USMT.
PHASE	Reports that a new phase in the migration is starting. This key can be one of the following values: Initializing Scanning Collecting Saving Estimating Applying
detectedUser	For the ScanState tool, this key is the users USMT detected on the source computer that can be migrated. For the LoadState tool, this key is the users USMT detected in the store that can be migrated.
includedInMigration	Defines whether the user profile/component is included for migration. Valid values are Yes or No.
forUser	Specifies either of the following values: The user state being migrated. This Computer, meaning files and settings that aren't associated with a user.
detectedComponent	Specifies a component detected by USMT. For ScanState, this key is a component or application that is installed on the source computer. For LoadState, this key is a component or application that was detected in the store.
totalSizeInMBToTransfer	Total size of the files and settings to migrate in megabytes (MB).
totalPercentageCompleted	Total percentage of the migration that is completed by either ScanState or LoadState.
collectingUser	Specifies which user ScanState is collecting files and settings for.
totalMinutesRemaining	Time estimate, in minutes, for the migration to complete.
error	Type of non-fatal error that occurred. This key can be one of the following values: UnableToCopy: Unable to copy to store because the disk on which the store is located is full. UnableToOpen: Unable to open the file for migration because another application or service has the file open in non-shared mode. UnableToCopyCatalog: Unable to copy because the store is corrupted. UnableToAccessDevice: Unable to access the device. UnableToApply: Unable to apply the setting to the destination computer.
objectName	The name of the file or setting that caused the non-fatal error.
action	Action taken by USMT for the non-fatal error. The values are: Ignore: Non-fatal error ignored and the migration continued because the /c option was specified on the command line. Abort: Stopped the migration because the /c option wasn't specified.
errorCode	The errorCode or return value.
numberOfIgnoredErrors	The total number of non-fatal errors that USMT ignored.
message*	The message corresponding to the errorCode.

List files log

The List files log (Listfiles.txt) provides a list of the files that were migrated. This list can be used to troubleshoot XML issues or can be retained as a record of the files that were gathered into the migration store. The List Files log is only available for ScanState.exe.

Diagnostic log

The diagnostic log can be obtained by setting the environment variable MIG_ENABLE_DIAG to a path to an XML file.

The diagnostic log contains:

Detailed system environment information.
Detailed user environment information.
Information about the migration units (migunits) being gathered and their contents.

Using the Diagnostic Log

The diagnostic log is essentially a report of all the migration units (migunits) included in the migration. A migunit is a collection of data. In the XML files, the component identifies the migunit that the migunit is associated with. The migration store is made up of all the migunits in the migration. The diagnostic log can be used to verify which migunits were included in the migration and can be used for troubleshooting while authoring migration XML files.

The following examples describe common scenarios in which the diagnostic log can be used.

Why is this file not migrating when I authored an "include" rule for it?

Let's imagine that we have the following directory structure and that we want the data directory to be included in the migration along with the New Text Document.txt file in the New Folder. The directory of C:\data contains:

12/21/2023  01:08 PM    <DIR>          .
12/21/2023  01:08 PM    <DIR>          ..
12/21/2023  01:08 PM    <DIR>          New Folder
12/21/2023  01:19 PM                13 test (1).txt
12/21/2023  01:19 PM                13 test.txt
               2 File(s)             26 bytes

The directory of C:\data\New Folder contains:

12/21/2023  01:08 PM    <DIR>          .
12/21/2023  01:08 PM    <DIR>          ..
12/21/2023  01:08 PM                 0 New Text Document.txt
               1 File(s)              0 bytes

To migrate these files the following migration XML is authored:

<?xml version="1.0" encoding="UTF-8"?>
<migration urlid="http://www.microsoft.com/migration/1.0/TestSuite_BUGFIX">

<component context="System"  type="Application">
  <displayName>DATA1</displayName>
  <role role="Data">
    <rules>
      <include>
        <objectSet>
          <pattern type="File">c:\data\ [*]</pattern>
        </objectSet>
      </include>

    </rules>
  </role>
</component>
</migration>

However, upon testing the migration, the New Text Document.txt file is noticed that it wasn't included in the migration. To troubleshoot this failure, the migration can be repeated with the environment variable MIG_ENABLE_DIAG set such that the diagnostic log is generated. Searching the diagnostic log for the component DATA1 reveals the following XML section:

<MigUnitList>
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)" Context="System" ConfidenceLevel="100" Group="Applications" Role="UserData" Agent="CMXEAgent" Selected="true" Supported="true">
    <Patterns Type="Include">
      <Pattern Type="File" Path="C:\data [*]"/>
    </Patterns>
  </MigUnit>
</MigUnitList>
<Perform Name="Gather" User="System">
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)">
    <Operation Name="Store" Type="File" Path="C:\data" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test (1).txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test.txt]" SimObj="false" Success="true"/>
  </MigUnit>
</Perform>

Analysis of this XML section reveals the migunit that was created when the migration rule was processed. The <Perform> section details the actual files that were scheduled for gathering and the result of the gathering operation. The New Text Document.txt file doesn't appear in this section, which confirms that the migration rule wasn't correctly authored.

An analysis of the XML elements library reference article reveals that the <pattern> tag needs to be modified as follows:

<pattern type="File">c:\data\* [*]</pattern>

When the migration is performed again with the modified tag, the diagnostic log reveals the following information:

<MigUnitList>
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)" Context="System" ConfidenceLevel="100" Group="Applications" Role="UserData" Agent="CMXEAgent" Selected="true" Supported="true">
    <Patterns Type="Include">
      <Pattern Type="File" Path="C:\data\* [*]"/>
    </Patterns>
  </MigUnit>
</MigUnitList>
<Perform Name="Gather" User="System">
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)">
    <Operation Name="Store" Type="File" Path="C:\data" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test (1).txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test.txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder [New Text Document.txt]" SimObj="false" Success="true"/>
  </MigUnit>
</Perform>

This diagnostic log confirms that the modified <pattern> value enables the migration of the file.

Why is this file migrating when I authored an exclude rule excluding it?

In this scenario, the following directory structure exists and all files in the Data directory should migrate, except for text files. The C:\Data folder contains:

Directory of C:\Data

12/21/2023  01:08 PM    <DIR>          .
12/21/2023  01:08 PM    <DIR>          ..
12/21/2023  01:08 PM    <DIR>          New Folder
12/21/2023  01:19 PM                13 test (1).txt
12/21/2023  01:19 PM                13 test.txt
               2 File(s)             26 bytes

The C:\Data\New Folder\ contains:

12/21/2023  01:08 PM    <DIR>          .
12/21/2023  01:08 PM    <DIR>          ..
12/21/2023  01:08 PM                 0 New Text Document.txt
               1 File(s)              0 bytes

The following migration XML is authored:

<?xml version="1.0" encoding="UTF-8"?>
<migration urlid="http://www.microsoft.com/migration/1.0/TestSuite_BUGFIX">

<component context="System"  type="Application">
  <displayName>DATA1</displayName>
  <role role="Data">
    <rules>
      <include>
        <objectSet>
          <pattern type="File">c:\data\* [*]</pattern>
        </objectSet>
      </include>
    </rules>
    <rules>
      <exclude>
        <objectSet>
          <pattern type="File">c:\* [*.txt]</pattern>
        </objectSet>
      </exclude>

    </rules>
  </role>
</component>

However, upon testing the migration, all the text files are noticed that they're still included in the migration. In order to troubleshoot this issue, the migration can be performed with the environment variable MIG_ENABLE_DIAG set so that the diagnostic log is generated. Searching the diagnostic log for the component DATA1 reveals the following XML section:

<MigUnitList>
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)" Context="System" ConfidenceLevel="100" Group="Applications" Role="UserData" Agent="CMXEAgent" Selected="true" Supported="true">
    <Patterns Type="Include">
      <Pattern Type="File" Path="C:\data\* [*]"/>
    </Patterns>
    <Patterns Type="Exclude">
      <Pattern Type="File" Path="C:\* [*.txt]"/>
    </Patterns>
  </MigUnit>
</MigUnitList>
<Perform Name="Gather" User="System">
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)">
    <Operation Name="Store" Type="File" Path="C:\data" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test (1).txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test.docx]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test.txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder [New Text Document.txt]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder [test.docx]" SimObj="false" Success="true"/>
  </MigUnit>
</Perform>

When the diagnostic log is reviewed, the files are still migrating is confirmed, and that it's a problem with the authored migration XML rule. An update is authored to the migration XML script as follows:

<?xml version="1.0" encoding="UTF-8"?>
<migration urlid="http://www.microsoft.com/migration/1.0/TestSuite_BUGFIX">

<component context="System"  type="Application">
  <displayName>DATA1</displayName>
  <role role="Data">
    <rules>
      <include>
        <objectSet>
          <pattern type="File">c:\data\* [*]</pattern>
        </objectSet>
      </include>
    </rules>
    <rules>
      <exclude>
        <objectSet>
          <pattern type="File">c:\data\* [*.txt]</pattern>
        </objectSet>
      </exclude>

    </rules>
  </role>
</component>


</migration>

The revised migration XML script excludes the files from migrating, as confirmed in the diagnostic log:

<MigUnitList>
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)" Context="System" ConfidenceLevel="100" Group="Applications" Role="UserData" Agent="CMXEAgent" Selected="true" Supported="true">
    <Patterns Type="Include">
      <Pattern Type="File" Path="C:\data\* [*]"/>
    </Patterns>
    <Patterns Type="Exclude">
      <Pattern Type="File" Path="C:\data\* [*.txt]"/>
    </Patterns>
  </MigUnit>
</MigUnitList>
<Perform Name="Gather" User="System">
  <MigUnit Name="\<System\>\DATA1 (CMXEAgent)">
    <Operation Name="Store" Type="File" Path="C:\data" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data [test.docx]" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder" SimObj="false" Success="true"/>
    <Operation Name="Store" Type="File" Path="C:\data\New Folder [test.docx]" SimObj="false" Success="true"/>
  </MigUnit>
</Perform>
