Upgrade VCSA 6.5 to 6.7

The last days VCSA 6.7.0a gets GA. In this post I want to show the upgrade from VCSA 6.5 U1 to VCSA 6.7.0 (not a). In my other post (Update VCSA 6.7) I’ve made the update from 6.7.0 to 6.7.0a.

First thing to know is, there is no support to upgrade from 6.5 U2 to 6.7.0! So, if you are planning to update your existing VCSA 6.5 to Update 2 you have to wait for the (maybe) VCSA 6.7 Update 1 to migrate to 6.7.

For example there is also no support from Veeam Backup & Replication 9.5 Update 3 for vSphere 6.7 (www.veeam.com) Support will come with the next update.

Now lets start with the upgrade

This check gives recommendations to updates for your software based on the underlying hardware configuration, the VMware Compatibility Gude and the vSAN Release Catalog. It also includes all necessary drivers and patches for the recommended release in its own vSAN system baseline.

In my homelab this new check gave me an alert and I want to disable it.

Upgrade the vSAN Witness Appliance

I’m using vSAN within my Homelab. In this post I explain the update (replacement) of the vSAN Witness Appliance. An update is a replacement in fact. You power up a new Witness Appliance, configures it, disable the Stretched Cluster and reconfigure this one with the new Witness.

Sounds to easy? But it is…
