Hello anonymous user

Welcome to Microsoft Q&A Platform,

Before you upgrade you can use the az aks get-upgrades command to check which releases are available for upgrade and see whether you can upgrade directly to 1.17.8.

If you have the chance it's better to test the upgrade first on a dev/test setup.

After the upgrade I'd recommend verifying the upgrade using the az aks show command.

More info below about this process:

I hope this helps!

Many thanks LuisRodriguez

Can I possibly ask a further question - apologies for this :)

I have 3 nodes that has OS that is out of support, Linux (ubuntu 16.04), and needs upgrading.

I would be really grateful if you can advise the method of upgrading the nodes - I am assuming upgrade of Kubernetes as outlined in the link you provided will not upgrade the OS as well.

I upgrading node OS will need to be done as a separate action before Kubernetes upgrade.

I look forward to your reply and advise
