4.12.5.Migration rules XML
You can modify the behavior of a migration by using XML files; these files provide instructions on where and how the USMT tools should gather and apply files and settings. USMT includes three XML files that you can use to customize a basic migration: the MigDocs.xml and MigUser.xml files, which modify how files are discovered on the source computer, and the MigApps.xml file, which is required in order to migrate supported application settings. You can also create and edit custom XML files to further customize your migration.
Save all the migration rule xml’s into the “usmt” folder within the Realm configuration directory. In the below image “r01” is the Realm name.
Include all of your .xml files as comma separated values (CSV).
