Objectives

Impact on the organization

Successful migration from OpenShift 3 to OpenShift 4 is a critical factor in maintaining continuity for customers with established workloads on legacy OpenShift 3. To preserve continued support and innovation, organizations must ensure a careful and precise transition of applications  using Red Hat’s tools and best practices. In comparison to OpenShift 3, OpenShift 4 brings in sophisticated automation, self-service, governance, and cloud-native features that are based on Kubernetes Operators to enable a wider variety of application modernization and digital transformation efforts.

Impact on the individual 

Learning to apply skills needed to migrate workloads from OpenShift 3 to OpenShift 4 using the Migration Toolkit for Containers will set up students to safely and correctly complete migrations in their organizations.
