Is there any maintenance (patches , upgrade for VMs created by DataBricks on Azure) from DataBricks

[Inna_M]

We are using Databricks on Azure. Infra team noticed we have some VMs created in the past for DataBricks clusters on version Linux (ubuntu 18.04). 

Is there maintenance previewed for that, upgrade? 

Are there any patches for created in Azure objects by DataBricks

and last.

I am recreating some clusters, in order to have VMs in supported version,

so I see a VM in older version, and cannot find the cluster it belongs to. What should I do in this case?

Thank you.

Finally while I was posting this question, AzureDataBricks upgraded VMs to the supported version 20, not the latest , 22. It was a week after old version was no longer supported by Microsoft
