Before uninstalling the server, consider the following:

1. Move the clients that the sever manages to an OfficeScan server with the same version. Consider creating a backup of the server database and configuration files if you plan to reinstall the server later.
2. Back up the OfficeScan database and import the configuration files before uninstalling the OfficeScan server. Back up the OfficeScan server database to a location outside the OfficeScan program directory. You can refer to these KB articles:
