Upgrade from 4.x to 5.x

This guide describes the steps to perform an upgrade of the component from version 4.x to 5.x.

The 5.x version changes the selector for alertmanager. The new selector won’t work for Kubernetes versions prior to 1.20 anymore. Therefore, before updating to version 5.x of this module, make sure to upgrade your cluster to at least 1.20.
