Upgrade NSX-T 2.4.0 to 2.4.1

We have installed NSX-T 2.4.0 and we want to upgrade to 2.4.1.

This article will show you how to conduct this upgrade

Upgrade Steps

Download upgrade bundle and upload it to the NSX–T Manager

First, we download the upgrade bundle from VMware

Then we upload the bundle into the "Upgrade" page of NSX-T.

After an approx. 20 minutes the upgrade bundle is fully uploaded and verified:

Begin the Upgrade

Now let's click on "Begin Upgrade"

Run pre–checks

Before we can actually start we first need to click on "Run Upgrade Pre-Checks".

The Edges had some pre-check warnings but nothing critical that we can not continue with the upgrade.

Upgrade hosts

Let's click "Next" to start the host upgrades first

Select them all and click on the "Start" button:

It was taking a very long time for NSX-T to put the hosts into maintenance mode and then I discovered that NSX-T could not power-off the VM's of my vApp automatically. So I did a manual power off of the full vApp:

And after I did this the install actually really began for the DC1 hosts:

For the DC2 hosts I needed to turn off the vApp as well:

And finally, the hosts were fully upgraded, after NSX-T has put them into maintenance mode and installed the NSX bits on them.

Upgrade Edge VM's

Let's click "Next" for the Edge upgrades and click on "Start" to start the upgrade:

And the edges are successfully upgraded as well:

Upgrade Controllers

Starting from NSX-T 2.4.0 the Manager and Controllers are collapsed and this means we don't have any separate controllers to upgrade, so this step will be skipped.
