For information about supported upgrade paths for FortiClient, see the FortiClient Release Notes.
For FortiClient in managed mode, an administrator may control FortiClient upgrades for you, and you may be unable to manually upgrade FortiClient. See EMS and automatic upgrade of FortiClient.
During a FortiClient upgrade to 6.0.9, FortiClient installs the same features that were previously installed. If you want to install different features, you must uninstall the previous version of FortiClient, and install FortiClient 6.0.9 with the desired features.
For FortiClient in managed mode, when an administrator deploys a FortiClient upgrade from EMS to endpoints running a Windows OS, an Upgrade Schedule dialog box displays in advance on the endpoint to let endpoint users schedule the upgrade and mandatory endpoint reboot. If no FortiClient is installed on the endpoint, no reboot is required for the installation, and no Upgrade Schedule dialog box displays. The endpoint user can postpone the reboot for a maximum of 24 hours. Before the mandatory reboot occurs, a FortiClient dialog box displays with a 15 minute warning.
