-Two Deployments with image for different versions are used togther. Both Deployments have same pod labels but differ in at least one label. The common pod labels are uesd as selector for the Service. Different pod labels are used to scale the number of replicas. One replica of the new version of Deployment is released alongside the old version.

Eventually, the old version is deleted.
