Procedure
- Perform a fresh installation of IMSS
9.1.

Tip
Trend Micro recommends importing configuration packages to a fresh installation of IMSS 9.1, because the imported configuration settings overwrite all existing settings. - Retrieve the package that contains the configuration settings that you wish to migrate.
- Go to on the IMSS 9.1 management
console. The Import/Export screen appears.
- Import the configuration package.

Note
By default, all child devices use the certificates of the parent device after migration. If you do not want to use those certificates, assign other certificates to child devices.
