To upgrade to NSX 6.2.x, you must upgrade the vCloud Networking and Security components in the order in which they are documented in this guide.
vCloud Networking and Security components must be upgraded to NSX in the following order:
Upgrade vShield Manager to NSX Manager
Deploy NSX Controller cluster - optional, required for logical (distributed) routers and changing control plane mode to hybrid or unicast
Update host clusters
Update Transport Zone - optional, if NSX Controller cluster is deployed, can change control plane mode to hybrid or unicast
Upgrade vShield App to NSX Distributed Firewall
Upgrade vShield Edge to NSX Edge
Upgrade vShield Endpoint to NSX Guest Introspection
The upgrade process is managed by the vShield Manager. If the upgrade of a component fails or is interrupted and you need to repeat or restart the upgrade, the process begins from the point at which it stopped; it does not start over from the beginning.
If you have virtual wires in your environment, once you have upgraded to NSX Manager you must update your host clusters.
