The Challenge
With Elastic's shift to proprietary licensing and rising costs, many organizations are looking for an open-source alternative that preserves API compatibility while offering a truly open ecosystem. OpenSearch provides exactly that — a community-driven, Apache 2.0-licensed platform that maintains compatibility with Elasticsearch while adding modern features like neural search, vector search, and built-in observability.
Migrating from Elasticsearch to OpenSearch requires careful planning around version compatibility, plugin migration, configuration differences, and zero-downtime cutover. Many organizations lack the expertise, time, or confidence to tackle these migrations independently, risking data loss, downtime, and suboptimal configurations that fail to leverage OpenSearch's full potential.
Why Migrate from
Elasticsearch to OpenSearch?
Truly Open Source
OpenSearch is released under the Apache 2.0 license, giving you complete freedom to use, modify, and distribute without vendor lock-in or surprise licensing changes. No more worrying about proprietary restrictions or escalating license fees.
High API Compatibility
OpenSearch maintains strong API compatibility with Elasticsearch, making migration straightforward for most applications. Your existing client libraries, queries, and integrations often work with minimal or no changes.
Modern AI-Powered Search
OpenSearch offers advanced capabilities including neural search, vector and semantic search, hybrid search, and machine learning-powered relevance. These features enable AI-driven applications and superior search experiences out of the box.
Fully Managed on AWS
Amazon OpenSearch Service provides a fully managed experience, eliminating operational overhead. Automated backups, patching, monitoring, and scaling let your team focus on building features instead of managing infrastructure.
Significant Cost Savings
By moving to OpenSearch, organizations typically see 30-50% cost reductions compared to Elastic Cloud or self-managed Elasticsearch deployments. Amazon OpenSearch Service pricing is transparent and predictable, with no per-node licensing fees.

Our Migration Approach
Discovery & Assessment
We begin with a thorough analysis of your Elasticsearch deployment, understanding your search use cases, index mappings, query patterns, plugin dependencies, and performance requirements. We identify compatibility considerations and opportunities for improvement in OpenSearch.
Compatibility & Plugin Mapping
Our experts map your Elasticsearch configurations to OpenSearch equivalents, addressing version-specific differences, plugin replacements, and client library updates. We ensure your queries, aggregations, and integrations work seamlessly on OpenSearch.
Data Migration & Validation
We design and execute data migration strategies, whether using snapshot/restore, reindexing, or cross-cluster replication. Comprehensive validation ensures data completeness, accuracy, and search quality matches or exceeds your current Elasticsearch deployment.
Cutover & Optimization
We manage the cutover process with minimal to zero downtime, using techniques like gradual traffic shifting and parallel running. Post- migration, we optimize performance, implement best practices, and leverage OpenSearch's advanced features for maximum value.
