Upgrading

Upgrading from previous EMS versions

EMS 7.2.1 only supports FortiClient 7.2 and 7.0. You must first upgrade older FortiClient versions to 7.0.7 or newer before upgrading EMS to 7.2.1.

FortiClient EMS supports direct upgrade from EMS 6.2, 6.4, and 7.0. To upgrade older EMS versions, follow the upgrade procedure in FortiClient and FortiClient EMS Upgrade Paths.

With the endpoint security improvement feature, there are backward compatibility issues to consider while planning upgrades. See Recommended upgrade path.

EMS 7.2.1 does not support legacy 158 licenses, which were in use before 2021 and have reached end-of-life. Following is a list of discontinued SKUs:

• FC1-15-EMS01-158-02-DD
• FC1-15-EMS02-158-02-DD

If you attempt an upgrade to EMS 7.2.1 with the legacy 158 licenses, the EMS installer displays an error message: "Legacy license is not supported after upgrade". The EMS upgrade does not proceed.

EMS 7.2.1 supports the following legacy Fabric Agent licenses to help customers with migration:

• FCX-15-EMS01-297-01-DD
• FCX-15-EMS01-298-01-DD
• FCX-15-EMS01-299-01-DD

You do not need to convert the aforementioned Fabric Agent licenses to upgrade to EMS 7.2.1.

Downgrading to previous versions

FortiClient EMS does not support downgrading to previous EMS versions.
