Note: The files store application and device configurations. The files are deleted
when you uninstall Device Registration Service software. If you do not back up
the files, you cannot recover the configurations and you have to manually
re-create them in the new version of Device Registration Service.
Note: Upgrading of DRS does not preserve all Windows settings (for example, the
security settings). It is recommended to validate that all settings are correct
after you start the DRS service.
Note: Tool will prompt the user to make changes to the file permissions.
Note: If the correct permissions have been granted and you still get a permissions
error reported during the upgrade, you will need to get a system admin to grant
temporary write access to the two files before the tool runs. Write access can
be revoked once the upgrade tool completes.
