Upgrading VMware NSX®Data Center for vSphere® to version 6.4.4 involves upgrading NSX Manager Appliance, NSX Controller cluster, NSX host clusters, and NSX Edge, in the order specified.



The upgrade process is managed by NSX Manager. If the upgrade of a component fails or is interrupted and you have to repeat or restart the upgrade, the process begins from the point at which it stopped. The upgrade process does not start over from the beginning.


  1. Upgrade the NSX Manager Appliance using the instructions at Upgrade NSX Manager.
  2. Upgrade NSX controllers using the instructions at Upgrade the NSX Controller Cluster.
  3. Upgrade the NSX host configuration using the instructions at Upgrade Host Clusters.
  4. Upgrade the NSX Edge appliance using the instructions at Upgrade NSX Edge.

    Edge Services Gateway instances can be upgraded at any time after the NSX Manager upgrade. However, logical routers cannot be upgraded until the NSX Controller cluster and host clusters have been upgraded. See the Operational Impacts of NSX Upgrades section of the NSX Upgrade Guide for more information about upgrade dependencies.
