Overview

Build comprehensive CI testing infrastructure for cross-management cluster restore scenarios
in HyperShift Hosted Control Planes. This Epic focuses specifically on validating the ability
to backup a HostedCluster in one management cluster and restore it in a different management
cluster.

Context

• Extension of OADP backup/restore integration work for cross-cluster scenarios
• Critical capability for disaster recovery and cluster migration use cases
• Need comprehensive CI coverage for cross-cluster restore across all providers
• Validates complete cluster portability between management clusters

Scope

This Epic covers implementation of E2E CI testing for:

• Cross-Management Cluster restore scenarios: Backup HostedCluster in source MGMT cluster,
  restore in target MGMT cluster
• All supported providers: AWS, Azure, KubeVirt, Agent, OpenStack, None, PowerVS
• Complex scenarios: Different provider configs, network topologies, and infrastructure
  between source and target

Acceptance Criteria

• CI strategy defined for cross-cluster restore testing (source/target cluster management)
• Ginkgo test structure established for cross-cluster restore scenarios
• Cross-cluster E2E tests implemented for AWS platform
• Cross-cluster E2E tests implemented for Azure platform
• Cross-cluster E2E tests implemented for KubeVirt platform
• Cross-cluster E2E tests implemented for Agent platform
• Cross-cluster E2E tests implemented for OpenStack platform
• Cross-cluster E2E tests implemented for None platform
• Cross-cluster E2E tests implemented for PowerVS platform
• CI jobs configured for cross-cluster testing with proper teardown
• Cross-cluster test documentation and runbooks completed

Benefits

• Validated disaster recovery capabilities across different management clusters
• Proven cluster migration and portability across infrastructure
• Enhanced business continuity for hosted control planes
• Comprehensive validation of OADP cross-cluster functionality
• Increased confidence in multi-cluster deployment strategies
