TSME 8.8 supports upgrading your configuration settings from the previous version 8.8.1 or 8.8.2.
Place your Microsoft Exchange server in maintenance mode because the Exchange Database and Exchange Transport services restart during the installation process.
TSME provides enhanced security by not supporting the HTML tags that have XSS vulnerability. Trellix recommends that you remove the HTML tags that have XSS vulnerability from the existing notification template before the upgrade. Otherwise, after the upgrade, if you try to modify the notification templates that contain unsupported tags, you will be prompted to remove the unsupported tags from the template or use the template without modification. For the list of unsupported HTML tags, see Trellix KnowledgeBase article KB82214.
When upgrading to a new version, you need not uninstall the existing version. The installation program updates your installation to the new version.
