Important: The Metasys Server is offline from when you uninstall the software to when you finish the upgrade or reinstallation. Be aware that if your historical databases are over 500 MB, the upgrade may take several hours to complete. Consider using the Metasys Database Manager or SQL Server software tools to purge your historical database before an upgrade. Refer to the Metasys Database Manager Help (LIT-12011202) for details.
