Should you’re working Apache Solr for search, now is a good time emigrate to Amazon OpenSearch Service. Amazon OpenSearch Serverless gives a contemporary, managed vacation spot that drastically reduces operational overhead. Migration Assistant for Amazon OpenSearch Service now helps Apache Solr sources from variations 6.x by way of 9.x. Migration Assistant now consists of an AI assistant which you can drive out of your most popular AI instruments. The assistant walks you thru the migration, offering an in depth report with timelines, blockers, schema and question translation.
On this put up, you’ll be taught why now’s the time to reap the benefits of the benefit of operations and native AI capabilities of OpenSearch Serverless, and migrate from Solr.
The problem of managing Solr
Many organizations have Solr deployments which have run for years, carrying accrued technical debt: older variations, customized patches, and operational processes originating with engineers who’ve left. Working Solr in manufacturing requires ongoing funding in upgrades, safety patches, monitoring, failure restoration, and capability planning. The operational burden compounds as your deployment ages and the engineers who constructed it transfer on, leaving the remaining group with a system that’s tough to change safely.
In the meantime, search has advanced. Customers work together by way of chat interfaces and AI brokers that synthesize data on their behalf. These patterns require semantic understanding, hybrid retrieval, and agentic capabilities like reminiscence and Mannequin Context Protocol (MCP) assist. OpenSearch is an open supply software program suite for search, analytics, and observability, licensed underneath the Apache License V2.0 and primarily based on Apache Lucene. OpenSearch supplies a broad and deep set of vector capabilities for AI workloads: a number of engines (Fb AI Similarity Search (FAISS) and Lucene), a number of algorithms (Hierarchical Navigable Small World (HNSW) and Inverted File (IVF)), quantization for value administration, hybrid search with rating normalization, neural sparse search, and a connector framework. You should utilize the OpenSearch connector framework to connect with your individual fashions hosted in companies corresponding to Amazon Bedrock and Amazon SageMaker. With these capabilities, you’ll be able to construct chat-based search, energy AI brokers, and implement Retrieval Augmented Era (RAG) workflows in your search engine.
Technical debt in customized patches and undocumented procedures could make delivery new options on Solr sluggish and dangerous. OpenSearch Serverless supplies a contemporary engine with all of the capabilities simply talked about, together with computerized scaling, and minimal infrastructure to keep up. Even in case you stay centered on conventional search, OpenSearch Serverless delivers related outcomes with much less operational effort.
OpenSearch Serverless simplifies search
Amazon OpenSearch Serverless alleviates infrastructure provisioning, capability planning, and information lifecycle administration. You create a group, ship information, and run queries. OpenSearch Serverless mechanically matches compute to your workload, independently scaling up indexing and search compute throughout spikes, and scaling compute to zero when idle. You pay just for storage when no requests are being processed. For variable site visitors patterns, OpenSearch Serverless can value as much as 60% much less than an OpenSearch Service area provisioned for peak.
The vector engine helps HNSW and IVF with FAISS and Lucene, plus quantization strategies to handle value as your assortment grows. With Automated Semantic Enrichment, you’ll be able to allow a sparse mannequin with a single setting to enhance textual content with vectors and enhance relevance with out constructing an embedding pipeline. GPU acceleration reduces HNSW index construct occasions from hours to minutes. OpenSearch Serverless additionally helps brokers and RAG workflows.
In case your workload requires tight management over infrastructure: particular occasion sorts, customized plugin configurations, or excessive scale past what serverless deployments goal, Amazon OpenSearch Service domains are the choice vacation spot. Domains provide you with full management over the cluster with one-click provisioning, patching, and backups. Migration Assistant helps each locations, so you’ll be able to decide the deployment mannequin that matches your workload with out altering your migration method.
Migration Assistant for Amazon OpenSearch Service
Migration Assistant has helped prospects transfer from self-managed Elasticsearch and OpenSearch to OpenSearch Service since December 2023. It now helps Solr sources. Migration Assistant now consists of an AI-assisted expertise which you can drive out of your most popular AI instruments, like Kiro, Claude Code, and others, to plan a migration, deploy the required infrastructure, and execute each historic and reside site visitors migration.
Traditionally, migrations required weeks of planning and assessments earlier than any information motion might start, and the method was typically error-prone. The AI-assisted expertise supplies an agent-guided workflow that helps you construction, execute, and validate your migration sooner and extra reliably. You should utilize Migration Assistant itself to do your evaluation, or join with the talents within the AWS Mannequin Context Protocol (MCP) server. Migration Assistant additionally now helps reside site visitors seize and replay for Solr, so you’ll be able to validate the brand new atmosphere with actual workloads earlier than slicing over.
Migration Assistant helps migrations to OpenSearch Serverless and OpenSearch Service domains from a variety of Solr, Elasticsearch, and OpenSearch variations. It’s open supply, so you need to use it for migrating to OpenSearch Serverless in all business AWS Areas and AWS GovCloud (US) Areas the place OpenSearch Serverless is obtainable.
Migrate now
OpenSearch Serverless offers you vector, hybrid, and semantic search, computerized scaling, scale-to-zero compute, and nil operational overhead. Migration Assistant for Amazon OpenSearch Service supplies the AI-assisted instruments to get there: plan with the agent, deploy the infrastructure, run a backfill out of your Solr backups, and validate with reside site visitors seize and replay earlier than you narrow over. Begin by pointing your AI instrument of option to Migration Assistant to get a plan, timeline, and price estimate.
