Migration
Migrate K3s Control Planes to Astra
Migrate K3s Control Planes to Astra
Recommended Approach
- Stand up Astra cluster and validate basic etcd API operations.
- Point a non-production K3s control-plane at Astra datastore endpoint.
- Replay representative workload and observe API/lease/list behavior.
- Compare against etcd baseline using the same harness profile.
- Promote only after passing workload-specific parity and SLO gates.
For deployment commands and topology layouts, use Deploy Astra + K3s (single node) and Deploy Astra + K3s (cluster).
Validation Priorities
- Lease lane stability under churn.
- LIST latency parity under high object cardinality.
- Resource profile (iowait, disk IOPS) under sustained reconcile loops.
Rollout Guidance
- Start with canary control-plane environments.
- Keep explicit rollback path to prior datastore until SLO confidence is established.
