Migration guides / Stack
From Elasticsearch to Obsfly
Elasticsearch's license change pushed many shops to OpenSearch.
Why teams switch
- Elasticsearch's license change pushed many shops to OpenSearch.
- OpenSearch is API-compatible for most read paths.
- AWS, Aiven, and self-hosted options are mature.
- Obsfly covers both equally — same dashboard set.
What Elasticsearch is genuinely good at
Fairness signal — useful in renewal conversations.
- Elasticsearch's commercial features (ML, anomaly detection, security) are deeper than OpenSearch's.
- If you depend on the proprietary ML jobs, the migration is harder.
Migration playbook
Step 1
Capture cluster baseline in Obsfly
Throughput by index, JVM heap, slow-log distribution, shard allocation.
Step 2
Stand up OpenSearch cluster
Reindex via cross-cluster replication or snapshot-restore.
Step 3
Validate query parity
Replay top index queries against OpenSearch; compare p99 in Obsfly.
Step 4
Migrate ingest pipelines
Most pipelines port without changes. Custom processors: validate per-pipeline.
Pitfalls to avoid
- Deep ML jobs: OpenSearch's anomaly detection is different from Elasticsearch's. Don't assume parity.
- Plugin ecosystem differs; audit your plugin set before cutover.
FAQ
- Does Obsfly support both?
- Yes — same metrics scraped from cluster health, JVM, slow log. UI is identical.
