UDM Upgrade Procedure

4 UDM Upgrade Procedure

Upgrading an existing UDM deployment, replaces the running containers and pods with new ones. If there is no change in the pod configuration, an existing deployment is not replaced. Unless there is a change in the service configuration of a micro service, the service endpoints remain unchanged (NodePort etc).

To upgrade UDM, perform the steps given below from a server that has access to Kubectl and helm commands.
