FortiClient version 6.2.6 supports upgrade from FortiClient versions 6.0 and later.
Starting with FortiClient 6.2.0, FortiClient EMS 6.2.0, and FortiOS 6.2.0, the FortiClient Endpoint Telemetry license is deprecated. The FortiClient Compliance profile under Security Profiles and the Enforce FortiClient Compliance Check option on the interface configuration pages have been removed from the FortiOS GUI. Endpoints running FortiClient 6.2.0 now register only with FortiClient EMS 6.2.0 and compliance is accomplished through the use of compliance verification rules configured on FortiClient EMS 6.2.0 and enforced through the use of firewall policies. As a result, there are two upgrade scenarios:
- Customers using only a FortiGate device in FortiOS 6.0 to enforce compliance must install FortiClient EMS 6.2.0 and purchase a FortiClient Security Fabric Agent License for their FortiClient EMS installation to continue using compliance features.
- Customers using both a FortiGate device in FortiOS 6.0 and FortiClient EMS running 6.0 for compliance enforcement must upgrade the FortiGate device to FortiOS 6.2.0, FortiClient to 6.2.0, and FortiClient EMS to 6.2.0.
FortiClient (macOS) 6.2.6 features are only enabled when connected to EMS 6.2.0. If FortiClient (macOS) 6.0 was previously running in standalone mode, ensure to install EMS 6.2.0, apply the license as appropriate, then connect FortiClient (macOS) to EMS before upgrading to FortiClient (macOS) 6.2.6. You should first upgrade any endpoint running a FortiClient (macOS) version older than 6.0.0 to 6.0.5 using existing 6.0 upgrade procedures.
See the FortiClient and FortiClient EMS Upgrade Paths for information on upgrade paths and order in which to upgrade Fortinet products.
