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, and Management plane.

The upgrade coordinator guides you through the proper upgrade sequence. You can track the upgrade process and if necessary you can pause and resume the upgrade process from the user interface.

The upgrade coordinator allows you to upgrade groups in a serial or parallel order. It also provides the option of upgrading the upgrade units within that group in a serial or parallel order.
