Feature Overview (aka. Goal Summary)  

OpenShift clusters that contain multiple architectures must be upgradable, in addition single architecture clusters need to be able to migrate to multi-architecture clusters

Goals (aka. expected user outcomes)

Use the standard OpenShift upgrade processes to move to a later OpenShift version regardless of the fact that it may be a multi-architecture cluster

Requirements (aka. Acceptance Criteria):

• Upgrade support including upgrade graphs
• Migration support
• Cluster Version spec changes

Use Cases (Optional):

Include use case diagrams, main success scenarios, alternative flow scenarios.  Initial completion during Refinement status.

Questions to Answer (Optional):

Include a list of refinement / architectural questions that may need to be answered before coding can begin.  Initial completion during Refinement status.

Out of Scope

Migration from a multi-architecture cluster to a single architecture cluster

Background

Provide any additional context is needed to frame the feature.  Initial completion during Refinement status.

Customer Considerations

Provide any additional customer-specific considerations that must be made when designing and delivering the Feature.  Initial completion during Refinement status.

Documentation Considerations

Provide information that needs to be considered and planned so that documentation will meet customer needs.  Initial completion during Refinement status.

Interoperability Considerations

Which other projects and versions in our portfolio does this feature impact?  What interoperability test scenarios should be factored by the layered products?  Initial completion during Refinement status.
