DO326 - Red Hat Openshift Migration Lab
Red Hat Openshift Migration Lab (DO326) is designed for OpenShift professionals migrating workloads from legacy deployments of OpenShift Container Platform running 3.11 onto a 4.6 installation. Students will gain practical working experience with the Migration Toolkit for Containers (MTC) to leverage in real-world migration scenarios.
- Assessing OpenShift 3 to OpenShift 4 migration scenarios.
- Discussion of OpenShift 4 subversion migration scenarios.
- Deploying the Migration Toolkit for Containers.
- Migrating Persistent Volumes application data between OpenShift clusters.
- Migrating application images from the internal registry between OpenShift clusters.
- Moving Kubernetes manifests application resources between OpenShift clusters.
- Migrating Kubernetes cluster settings between OpenShift clusters.
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.
- Red Hat consultants and partners responsible for customer success and who want to migrate from OpenShift 3 to OpenShift 4.
- OpenShift professionals responsible for the transition of workloads onto OpenShift 4
- Planning an OpenShift 3 to 4 migration
- Preparing the target cluster for migration
- Deploying the Migration Toolkit for Containers (MTC)
- Migrating applications using the MTC
- Mapping application dependencies and dandling migration issues
- Automating application migrations using the MTC API and Ansible
- Reducing downtime during a migration process
- Red Hat OpenShift 3 to 4 migration lab comprehensive review
- Red Hat OpenShift I: Containers & Kubernetes (DO180) and Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) are required prerequisites for DO326 because they teach the OpenShift administration and Kubernetes skills necessary to comprehend and use the MTC
- Red Hat OpenShift Installation Lab (DO322) and Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise (DO380) are suggested as either prerequisites or follow-ups for DO326 because they teach how to deploy and customize OpenShift 4 clusters to meet security, availability, and performance requirements of different workloads.
