Upgrading NSX controller node

If you have network virtualization features, such as VXLAN and distributed routing implemented, you will need to upgrade the NSX Controller Nodes after the NSX Manager(s) are upgraded. It is recommended to upgrade the NSX Controller Nodes during the same maintenance window as the NSX Manager(s) upgrade.

Note

If you only have a vShield endpoint or a distributed firewall-only deployment, you may skip this recipe and jump straight to the Upgrading VMware NSX Host Clusters recipe.

At this stage, you should have completed your NSX Manager upgrade, including all the Secondary NSX Managers, if you are running a Cross-vCenter setup. In addition, the following prerequisites need to be satisfied:

• VMware requires that each NSX controller cluster has three controller nodes. Make sure you have three NSX Controller Nodes; if you have fewer than three nodes, add the remaining additional nodes before starting the upgrade.
• Make sure that all the NSX Controller Nodes are in the cluster...
