You must upgrade Virtual Wires from a 5.5 environment to NSX logical switches to use NSX features. You must follow this procedure even if you do not have Virtual Wires in your environment so that network virtualization components can be installed.

vShield Manager has been upgraded to NSX Manager.

It is recommended that you upgrade to logical switches in a datacenter maintenance window.

1

Log in to the vSphere Web Client.

2

Click Networking & Security and then click Installation.

3

Click the Host Preparation tab.

All clusters in your infrastructure are displayed.

If you had Virtual Wires in your 5.5 environment, the Installation Status column displays legacy, Update, and Uninstall.

4

For each cluster, click Update or Install in the Installation Status column.

Each host in the cluster receives the new logical switch software.

5

Monitor the installation till the Installation Status column displays a green check mark

6

If the Installation Statuscolumn displays a red warning icon and says Not Ready, click Resolve. If the installation is still not successful, click the warning icon. All errors are displayed. Take the required action and click Resolve again.

NSX reboots the hosts after moving them to maintenance mode and leveraging DRS to vMotion active virtual machines to other hosts. In case an error message is displayed, you may need to reboot the hosts in the cluster manually or take other action according to the error message.

While the upgrade is in progress, do not deploy, upgrade, or uninstall any service or component.

All virtual wires from your 5.5 infrastructure are upgraded to NSX logical switches and the VXLAN column for the cluster says Enabled. You can now add a controller and change the control plane setting for the transport zone to Unicast or Hybrid at the logical switch level or transport zone level.
