You can skip upgrading NSX Tools for reasons listed here.

Except under the following scenarios, do not skip the upgrade of NSX Tools because VMs with NSX Tools in a different version compared to PCG will lose connectivity with the PCG.

Scenarios for skipping NSX Tools upgrade:

  • You want to upgrade only selected private clouds within your public cloud.
  • You do not want any downtime on certain critical managed workload VMs.
  • You do not want powered off VMs to block the upgrade process.
  • You might want to apply a bug-fix patch only to the PCG without affecting NSX Tools.
