What Elasticsearch migrations do you handle?

Elasticsearch → OpenSearch (cost, AWS-residency or feature-driven; note Elastic re-added the OSI-approved AGPLv3 in 2024, so licensing alone is rarely the forcing function anymore), self-managed → Elastic Cloud or Elastic Cloud Enterprise onboarding, Elastic Cloud → Amazon OpenSearch Service (cost-driven migrations), ES 7.x → 8.x version upgrades (with breaking-change handling), index reindexing for major version jumps, Kibana → OpenSearch Dashboards conversion. For the engine-decision phase, see our Elasticsearch consulting service.

ES → OpenSearch — what's the playbook?

First confirm the driver: since Elastic re-added the OSI-approved AGPLv3 in 2024 (alongside Elastic License 2.0 and SSPL), Elasticsearch is open-source again for many buyers, so most OpenSearch moves are now cost, AWS-residency or Apache-2.0-feature driven rather than licensing-forced. From ES 7.10: snapshot/restore migrates cleanly (same lineage point as OpenSearch fork). From ES 8.x: reindex-from-remote is required because index formats diverged. Query DSL is mostly compatible since 2021 but with edge cases — validate against staging. Dashboards: Kibana 7.10 imports cleanly to OpenSearch Dashboards; 8.x Kibana dashboards need manual conversion. Security plugin migration (X-Pack Security → OpenSearch Security, forked from Search Guard) has different config models and is usually the largest piece of work.

ES 7.x → 8.x upgrade — what breaks?

Major version jumps have breaking changes: removal of mapping types (you should have moved off these by 8.x anyway), tightened security defaults (TLS required, security on by default), removed legacy clients, deprecated APIs cleaned up. Index format incompatibility means you can't directly upgrade indices created before 7.0; reindex required. We audit existing usage against 8.x breaking changes before any upgrade timeline gets committed.

Elastic Cloud onboarding — what's the path?

Self-managed → Elastic Cloud: snapshot to S3-compatible storage, restore on Elastic Cloud deployment. Sizing: pick deployment template (Hot-warm-cold-frozen tier ratios), allocate JVM heap (50% of node RAM up to 31GB), configure replicas. Pricing-wise: Elastic Cloud is per-RCU (Resource Component Unit) — model against your actual data + query throughput. For multi-cloud, Elastic Cloud runs on AWS/Azure/GCP with consistent pricing.

Cost migration — Elastic Cloud → Amazon OpenSearch Service?

Common for AWS-resident workloads where Amazon OpenSearch Service pricing (~30% cheaper for equivalent workloads) tips the math. Path: snapshot to S3 → Amazon OpenSearch Service import. Feature-gap audit critical: ELSER (Elastic-only), ESQL (Elastic-only), Universal Profiling (Elastic-only) don't exist on OpenSearch. For workloads using only standard ES features, migration is feasible; for ELSER-heavy RAG workloads, the migration may require replacing the retrieval architecture.

Kibana → OpenSearch Dashboards conversion?

OpenSearch Dashboards is a fork of Kibana 7.10. From Kibana 7.10: dashboards import cleanly. From Kibana 8.x: significant manual conversion — Elastic-proprietary apps (APM, Synthetics, ESQL editor, Universal Profiling) don't exist in OpenSearch Dashboards. Index pattern semantics differ slightly. We do a dashboard inventory + conversion-effort estimate before committing to the migration timeline.

Cutover playbook for zero-downtime?

Standard: (1) provision target with sized topology, (2) take snapshot of source to shared snapshot repo, (3) restore on target, (4) configure cross-cluster replication for catch-up writes, (5) wait for replication lag to settle, (6) flip reads to target — observe query latency + error rate, (7) quiesce writes on source briefly, (8) promote target, (9) cut application endpoints, (10) 24-48 hour soak with source kept replicated as rollback, (11) decommission source.

Sound familiar?

▸ SSPL/ELv2 licensing block forces ES → OpenSearch and the migration timeline is approved, but the security-plugin + Kibana dashboard conversion scope needs design.
▸ Elastic Cloud → Amazon OpenSearch Service for cost — but ELSER / ESQL / Universal Profiling feature gaps need an audit first.
▸ ES 7.x → 8.x upgrade is overdue — breaking changes + index reindex need planning before code ships.

Tested cutover playbooks with replication-lag gates

Elasticsearch Migration Services

In short: An Elasticsearch migration covers ES → OpenSearch (SSPL/ELv2-driven), Elastic Cloud onboarding, Amazon OpenSearch Service cost moves, ES 7.x → 8.x upgrades, and Kibana dashboard conversion. Each runs snapshot/restore or reindex-from-remote, a security-plugin and feature-gap audit, then a replication-lag-monitored cutover with a defined rollback procedure.

ES → OpenSearch SSPL/ELv2-driven cutover, Elastic Cloud onboarding, Amazon OpenSearch Service cost migration, ES 7.x → 8.x version upgrades, Kibana dashboard conversion — with replication-lag-monitored cutovers. See Elasticsearch consulting for the architecture-decision phase or the ES vs OpenSearch comparison.

Runbooks

Elasticsearch migrations we handle

Each path has a tested runbook — snapshot/restore cutover, replication-lag gating, defined rollback procedure.

ES → OpenSearch

Cost, AWS-residency or Apache-2.0-feature driven (Elastic re-added AGPLv3 in 2024). From ES 7.10 clean snapshot/restore; from 8.x reindex-from-remote. Security plugin migration is the largest piece.

Elastic Cloud Onboarding

Self-managed → Elastic Cloud (multi-cloud), sizing via Resource Component Units, tier template selection, snapshot-and-restore cutover.

Elastic Cloud → Amazon OpenSearch Service

Cost-driven migration for AWS-resident workloads. Feature-gap audit critical — ELSER/ESQL/Universal Profiling don't exist on OpenSearch.

ES 7.x → 8.x Upgrade

Breaking-change audit (mapping types, security defaults, deprecated APIs), index reindex for pre-7.0 data, application-tier validation.

Kibana → OpenSearch Dashboards

Dashboard inventory + conversion-effort estimate. Kibana 7.10 imports cleanly; 8.x requires manual conversion for Elastic-proprietary apps.

Index Reindexing

Major version jumps with index format incompatibility, reindex-from-remote orchestration, alias-cutover patterns for zero-downtime.
