BUT:

If you have deployed a Prism Central and want to update you get an error about an unsupported version in Prism Central Upgrade Section.

To solve that do the following:

Unregister your cluster from Prism Central (2 Times ssh on one of your CVMs, onetime on your Prism Central CVM). Read this article: https://next.nutanix.com/prism-infrastructure-management-26/unregister-a-prism-central-37829

You should grab your Cluster-UUID and Prism Central UUID via “ncli cluster state” first!

Step 1:

Login to one of your cvm in a running cluster.

  •  Check Cluster Status with “cluster status” 
  • Do “ ncli multicluster remove-from-multicluster external-ip-address-or-svm-ips=Prism-Central-IP username=PrismCentral-User password=password force=true”
  • Login to Prism Central CVM and unregister the Cluster
  •  “python /home/nutanix/bin/unregistration_cleanup.py UUID-of-your-cluster”
  • Login to one of your CVMs again
  • “ python /home/nutanix/bin/unregistration_cleanup.py UUID-of-your-PrismCentral”

Step 2:

In the Webinterface of Prism Element no PrismCentral is registered now and also no Cluster in Prism Central

 

Step 3:

Upgrade your PrismCentral with Metadatafile and tar Archiv for PrismCentralUpdate

Stepf 4:

Upgrade your Prism Element with MetadataFile and Archiv für PrismCE Update

Step 5:

Register back your Cluster via Prism Element Webinterface to Prism Central

 

Enjoy
