Office setup and migration considerations

Because of the way that user settings are stored in the registry, USMT 4.0 can only migrate Office settings from an x64-based installation of Office to an x64-based installation of Office, or from an x86-based installation of Office to an x86-based installation of Office. Additionally, USMT 4.0 cannot migrate the Microsoft Word settings in the following registry key:


USMT does not support migrating settings to a version of Office that is earlier than the version that is currently installed on the source computer. For example, USMT 4.0 cannot migrate settings from an Office 2007 installation to an Office 2003 installation.


To migrate application settings by using USMT 4.0, install applications on the destination computer before you run the LoadState command. For Office installations, you must run the LoadState command to apply settings before you start Office on the destination computer for the first time. If you start Office for a user before you run the LoadState command, many settings of Office will not migrate correctly. For more information, see Introduction to the best practices for USMT (
