In the event you’re operating Apache Solr for search, now is a good time emigrate to Amazon OpenSearch Service. Amazon OpenSearch Serverless presents a contemporary, managed vacation spot that tremendously reduces operational overhead. Migration Assistant for Amazon OpenSearch Service now helps Apache Solr sources from variations 6.x by means 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 publish, you’ll study why now could be the time to make the most 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 collected technical debt: older variations, customized patches, and operational processes originating with engineers who’ve left. Operating 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 staff with a system that’s tough to switch safely.
In the meantime, search has developed. Customers work together by means 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) help. OpenSearch is an open supply software program suite for search, analytics, and observability, licensed beneath the Apache License V2.0 and based mostly on Apache Lucene. OpenSearch gives 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 need to use the OpenSearch connector framework to connect with your individual fashions hosted in companies equivalent to Amazon Bedrock and Amazon SageMaker. With these capabilities, you may construct chat-based search, energy AI brokers, and implement Retrieval Augmented Technology (RAG) workflows in your search engine.
Technical debt in customized patches and undocumented procedures could make delivery new options on Solr gradual and dangerous. OpenSearch Serverless gives a contemporary engine with all of the capabilities simply talked about, together with automated scaling, and minimal infrastructure to keep up. Even in the event 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 routinely 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 methods to handle value as your assortment grows. With Computerized Semantic Enrichment, you may 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 varieties, 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 may choose 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 usually error-prone. The AI-assisted expertise gives an agent-guided workflow that helps you construction, execute, and validate your migration sooner and extra reliably. You need to use Migration Assistant itself to do your evaluation, or join with the abilities within the AWS Mannequin Context Protocol (MCP) server. Migration Assistant additionally now helps reside site visitors seize and replay for Solr, so you may validate the brand new surroundings with actual workloads earlier than reducing over.
Migration Assistant helps migrations to OpenSearch Serverless and OpenSearch Service domains from a spread of Solr, Elasticsearch, and OpenSearch variations. It’s open supply, so you need to use it for migrating to OpenSearch Serverless in all industrial AWS Areas and AWS GovCloud (US) Areas the place OpenSearch Serverless is accessible.
Migrate now
OpenSearch Serverless provides you vector, hybrid, and semantic search, automated scaling, scale-to-zero compute, and 0 operational overhead. Migration Assistant for Amazon OpenSearch Service gives 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 value estimate.
