Epic Goal

This is a followup to https://issues.redhat.com/browse/OPNET-508 which was an investigation into whether we can migrate from configure-ovs to NMState management of br-ex in an existing cluster. The initial results were not positive (it created conflicts in the OVS database), although we have had some success with an alternative process since then.

The goal of this work is to come up with a supportable process for migrating from configure-ovs to NMState after initial deployment of a cluster.

Why is this important?

Users with existing clusters also want to take advantage of the benefits of managing br-ex with NMState. Currently they would need to redeploy from scratch, but if this is implemented they would be able to do so in existing clusters.

Planning Done Checklist

The following items must be completed on the Epic prior to moving the Epic from Planning to the ToDo status

• Priority+ is set by engineering
• Epic must be Linked to a +Parent Feature
• Target version+ must be set
• Assignee+ must be set
• (Enhancement Proposal is Implementable
• (No outstanding questions about major work breakdown
• (Are all Stakeholders known? Have they all been notified about this item?
• Does this epic affect SD? {}Have they been notified{+}? (View plan definition for current suggested assignee)
  1. Please use the “Discussion Needed: Service Delivery Architecture Overview” checkbox to facilitate the conversation with SD Architects. The SD architecture team monitors this checkbox which should then spur the conversation between SD and epic stakeholders. Once the conversation has occurred, uncheck the “Discussion Needed: Service Delivery Architecture Overview” checkbox and record the outcome of the discussion in the epic description here.
  2. The guidance here is that unless it is very clear that your epic doesn’t have any managed services impact, default to use the Discussion Needed checkbox to facilitate that conversation.
