Hi there!

We plan to support upgrades to minor versions in the future(1.14 -> 1.15). For the time being in order change minor versions, creating a new cluster is required.

Regards,

John Kwiatkoski
Senior Developer Support Engineer

Note that if you recreate the cluster, then you will lose your external IP. So you will have to update your DNS. That’s what I understand. See https://www.digitalocean.com/community/questions/how-to-reuse-do-loadbalancer-previously-created-through-kubernetes
