View source for Upgrade NSX-T 2.4.0 to 2.4.1

== Introduction ==

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 [https://www.vmware.com 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:

[[File:upgrade-nsxt-cluster-25062019-20.png|800px]]

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

[[File:upgrade-nsxt-cluster-25062019-22.png|800px]]

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:

[[File:upgrade-nsxt-cluster-25062019-25.png|800px]]

[[File:upgrade-nsxt-cluster-25062019-26.png|800px]]

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.

[[File:upgrade-nsxt-cluster-25062019-28.png|800px]]

Let's click next and start with the Managers/Controllers upgrade

==== Upgrade Managers/Controllers ====

Click "Start" again here:

[[File:upgrade-nsxt-cluster-25062019-31.png|800px]]

At some point the page you are upgrading from will be unavailable:

[[File:upgrade-nsxt-cluster-25062019-32.png|800px]]

But after 10 minutes you should be able to log back in.

[[File:upgrade-nsxt-cluster-25062019-34.png|800px]]

After a quick check if my cluster is still healthy I noticed that two of the three nodes had a high CPU load.

[[File:upgrade-nsxt-cluster-25062019-35.png|800px]]

[[File:upgrade-nsxt-cluster-25062019-36.png|800px]]

And after another 10 minutes I saw that the "SYnc" was in progress:

[[File:upgrade-nsxt-cluster-25062019-37.png|800px]]

And the sync was completed:

[[File:upgrade-nsxt-cluster-25062019-38.png|800px]]

[[File:upgrade-nsxt-cluster-25062019-39.png|800px]]

When I wanted to go back to the "upgrade" page I got this error message:

[[File:upgrade-nsxt-cluster-25062019-40.png|800px]]

But it just needed some time to start the services and here we can see the final page that every component is nicely upgraded from 2.4.0 to 2.4.1.
