FortiClient EMS 6.2.3 supports upgrading from previous EMS versions as outlined in FortiClient and FortiClient EMS Upgrade Paths.
Before any version upgrade or other maintenance, remember to back up the EMS database. Consider performing a full server backup or taking a VM snapshot if possible.
When upgrading FortiClient EMS from 6.0 to 6.2.3, EMS retains the 6.0 license after the upgrade. However, due to the major licensing changes introduced in 6.2.0, you must still convert the license to a 6.2 license by manually converting the license on the Customer Service & Support site by August 31, 2020, or by contacting the Fortinet Support team. After the converted license expires, you must order and apply 6.2 licenses.
