Chapter 2. About migrating from OpenShift Container Platform 3 to 4
OpenShift Container Platform 4 contains new technologies and functionality that result in a cluster that is self-managing, flexible, and automated. OpenShift Container Platform 4 clusters are deployed and managed very differently from OpenShift Container Platform 3.
The most effective way to migrate from OpenShift Container Platform 3 to 4 is by using a CI/CD pipeline to automate deployments in an application lifecycle management framework.
You can use Red Hat Advanced Cluster Management for Kubernetes to help you import and manage your OpenShift Container Platform 3 clusters easily, enforce policies, and redeploy your applications.
