Upgrade NSX-T 2.5.1 to 3.0

Please find the step-by-step process for upgrading NSX-T 2.5.1 to 3.0 

1) Download NSX Cloud Upgrade Bundle for NSX-T 3.0.0 from Vmware.com website.

2)  Log into NSX-T Manager Node (DO NOT USE VIP)

Go to System -> Upgrade -> Upload MUB file -> {Select file} -> Upload

nsxt-u1

This will upload the bundle, extract it and display a "BEGIN UPGRADE" if successful

2) When uploaded click Begin Upgrade  -. Continue -> Continue

3) Select RUN PRE CHECKS

Note: This threw up an error about adding a 100GB to each NSX Manager Node

To do this log into the VCSA and on each NSX Manager Node -> Edit Settings -> Add New Device -> Hard Disk {w/ configuration of 100GB – thin provision)

Then back on to the upgrade page and click Run Pre-checks again.

 

The click Next -> Then Start on the Edges section

You will see the following page:

Note: I'd left this running and when i came back my browser had timed out but I was able to see that it had completed and was able to resume the upgrade.

On the hosts tab -> start

nsxt-u7

Note: Serial option will do one host after another by putting each in maintenance mode and install the new NSX-T VIBs

nsxt-u8

Once complete  you can then move onto the maangement nodes by pressing Next -> Start

You'll see a status during the upgrade.

Note: During the upgrade I was kicked out of the process with the following error on the NSX-T manager nodes:

Some appliance components are not functioning properly

 

nsxt-u10

Just give this several minutes and the node services will eventually restart.

Upon logging back it was still showing as "Upgrade In Progress"

The process takes some time and I was kicked out again.  You can check the status of the update by connecting to a node via SSH and running the following command:

get upgrade progress-status

In the below I connected to the two secondary nodes and got the following:

nsxt-u12

 

I followed the upgrade process of the node1 and could see the following status

Name: run_migration_tool
State: TASK_IN_PROGRESS

nsxt-u13

 

At this point I could ping all nodes but was unable to view the gui (or telnet on port 443)

The next stage appeared to be starting the NSX manager service

nsxt-u14

At this point I was able to see port 443 was open on node 1 but not on the others

Extra checks showed the following.(at this point I was still unable to access any GUI)

nsxt-u15

I then logged into other other managers via SSH and could see the start_manager status. Once they were complete i logged back into node1 and could see the next status was restore_datastore_cluster then update_upgrade_status. The final status was Upgrade is not in progress

I then logged into the GUI and could see the following:

Great. The upgrade worked. Click around and see the new features and views. To confim the appliances have been updated click system -> appliance
