After you finish the prerequisites for upgrading, your next step is to update the upgrade coordinator to initiate the upgrade process.
Trending support issues in VMware NSX (2131154) – This article provides information regarding trending issues and important Knowledge Base articles regarding VMware NSX Data Center for vSphere 6.x and VMware NSX-T Data Center 3.x.
The upgrade coordinator runs in the NSX Manager. It is a self-contained web application that orchestrates the upgrade process of hosts, NSX Edge cluster, NSX Controller cluster, and Management plane.
After the upgrade coordinator has been upgraded, based on your input, the upgrade coordinator updates the NSX Edge cluster, hosts, and the Management plane. Edge upgrade unit groups consist of NSX Edge nodes that are part of the same NSX Edge cluster. You can reorder Edge upgrade unit groups and enable or disable an Edge upgrade unit group from the upgrade sequence.
You can upgrade your hosts using the upgrade coordinator.
The upgrade sequence upgrades the Management Plane at the end. When the Management Plane upgrade is in progress, avoid any configuration changes from any of the nodes.
