To upgrade a VMware NSX® Intelligence™ 1.0 appliance to a later version, you must use the NSX Intelligence 1.0 command-line interface (CLI). When upgrading an NSX Intelligence 1.1 or later appliance, you must use the NSX Manager user interface (UI).

Important: If your current NSX-T Data Center environment includes an older NSX Intelligence version and you want to upgrade to a later non-maintenance release version of NSX-T Data Center, you must upgrade the NSX Intelligence appliance first.

Only an in-place upgrade mode is supported. All the NSX Intelligence services and user interface are not available during the upgrade. All the configuration files and all the data from the /data partition of the NSX Intelligence appliance node are retained. There is no network traffic data migration support available.
