Example 1: Migrating an unsupported application

The following is a template for the sections that you will need to migrate your own application — it is not functional, but you can use it to write your own .xml file.

<migration urlid="https://www.microsoft.com/migration/1.0/migxmlext/migapp">
  <component type="Application">
    <!-- Name of the application -->
    <displayName>Some Application</displayName>
    <!-- Specify whether the environment variables exist in the context of user or system or both -->
    <environment context="System">
      <!-- create the environment variables -->
      <variable name="myVar1">
        <!-- simple text value assignment to a variable -->
        <text>value</text>
      </variable>
      <variable name="myAppExePath">
        <!-- make a call to in-built helper function to get a value from a reg key and assign that value to the variable -->
        <script>MigXmlHelper.GetStringContent("Registry","HKLM\Software\MyApp\Installer [EXEPATH]")</script>
      </variable>
    </environment>
    <role role="Settings">
      <detects>
        <!-- all of these checks must be true for the component to be detected -->
        <detect>
          <!-- make a call to in-built helper function to check to see if an object exists or not -->
          <condition>MigXmlHelper.DoesObjectExist("Registry","HKLM\Software\MyApp [win32_version]")</condition>
        </detect>
        <detect>
          <!-- either of these checks must be true for the component to be detected -->
          <!-- make a call to in-built helper function to check to see if a file version matches or not -->
          <condition>MigXmlHelper.DoesFileVersionMatch("%MyAppExePath%","ProductVersion","8.*")</condition>
          <condition>MigXmlHelper.DoesFileVersionMatch("%MyAppExePath%","ProductVersion","9.*")</condition>
        </detect>
      </detects>
      <!-- describe the rules that will be executed during migration of this component and the context, whether user, system or both -->
      <rules context="User">
        <!-- delete objects specified in the object set on the destination machine before applying source objects -->
        <destinationCleanup>
          <!-- describe the pattern for the list of objects to be deleted -->
          <objectSet>
            <pattern type="Registry">HKCU\Software\MyApp\Toolbar\* [*]</pattern>
            <pattern type="Registry">HKCU\Software\MyApp\ListView\* [*]</pattern>
            <pattern type="Registry">HKCU\Software\MyApp [ShowTips]</pattern>
          </objectSet>
        </destinationCleanup>
        <!-- specify which set of objects should be migrated -->
        <include>
          <!-- describe the pattern for the list of objects to be included -->
          <objectSet>
            <pattern type="Registry">HKCU\Software\MyApp\Toolbar\* [*]</pattern>
            <pattern type="Registry">HKCU\Software\MyApp\ListView\* [*]</pattern>
            <pattern type="Registry">HKCU\Software\MyApp [ShowTips]</pattern>
          </objectSet>
        </include>
        <!-- specify which set of objects should not be migrated -->
        <exclude>
          <!-- describe the pattern for the list of objects to be excluded from migration -->
          <objectSet>
            <pattern type="Registry">HKCU\Software\MyApp [Display]</pattern>
          </objectSet>
        </exclude>
      </rules>
    </role>
  </component>
</migration>

Example 2: Migrating the My Videos folder

The following is a custom .xml file named CustomFile.xml that migrates My Videos for all users (if the folder exists on the source computer).

Code	Behavior
`<condition>MigXmlHelper.DoesObjectExist("File","%CSIDL_MYVIDEO%")</condition>`	Verifies that My Videos exists on the source computer.
`<include filter='MigXmlHelper.IgnoreIrrelevantLinks()'>`	Filters out the shortcuts in My Videos that do not resolve on the destination computer. This has no effect on files that are not shortcuts. For example, if there is a shortcut in My Videos on the source computer that points to C:\Folder1, that shortcut will only be migrated if C:\Folder1 exists on the destination computer. However, all other files (for example .mp3 files) migrate without any filtering.
`<pattern type="File">%CSIDL_MYVIDEO%\* [*]</pattern>`	Migrates My Videos for all users.

<component type="Documents" context="User">
        <displayName>My Video</displayName>
        <role role="Data">
            <detects>           
                <detect>
                    <condition>MigXmlHelper.DoesObjectExist("File","%CSIDL_MYVIDEO%")</condition>
                </detect>
            </detects>
            <rules>
                <include filter='MigXmlHelper.IgnoreIrrelevantLinks()'>
                    <objectSet>
                        <pattern type="File">%CSIDL_MYVIDEO%\* [*]</pattern>
                    </objectSet>
                </include>
           </rules>
        </role>
    </component>
</migration>

Example 3: Migrating files and registry keys

This table describes the behavior in the following example .xml file.

Code	Behavior
`<pattern type="File">%ProgramFiles%\USMTTestFolder\* [USMTTestFile.txt]</pattern>`	Migrates all instances of usmttestfile.txt from all sub-directories under %ProgramFiles%\USMTTestFolder.
`<pattern type="File">%ProgramFiles%\USMTDIRTestFolder\* [*]</pattern>`	Migrates the whole directory under %ProgramFiles%\USMTDIRTestFolder.
`<pattern type="Registry">HKCU\Software\USMTTESTKEY\* [MyKey]</pattern>`	Migrates all instances of MyKey under HKCU\Software\USMTTESTKEY.
`<pattern type="Registry">HKLM\Software\USMTTESTKEY\* [*]</pattern>`	Migrates the entire registry hive under HKLM\Software\USMTTESTKEY.

Example 4: Migrating specific folders from various locations
