NextBrick
NEXTSEARCH MIGRATION PROGRAM

Migrate Apache Solr to NextSearch 2.3

Keep the search engineering discipline. Gain a modern operator experience for migration, hybrid retrieval, AI-assisted workflows, and production operations.

Solr modernization

Benchmark the move before you commit.

Nextbrick maps your Solr workload to NextSearch 2.3, tests it with production-shaped data and queries, and gives your team measurable acceptance criteria before cutover.

Migration path

From Solr inventory to a supported NextSearch launch

01

Assess

Inventory collections, schemas, analyzers, query parsers, plugins, ingestion paths, traffic, and SolrCloud requirements.

02

Prove

Load production-shaped data into NextSearch 2.3 and compare compatibility, relevance, latency, throughput, and resource use.

03

Migrate

Move data and integrations in controlled stages, verify field parity, and rehearse cutover with a tested rollback plan.

04

Operate

Run cluster health, index administration, Query DSL, hybrid retrieval, and AI-assisted operations from one workspace.

What changes

A migration target built around the operator

Preserve the search behavior that matters while moving validation, retrieval, and operations into one NextSearch 2.3 workflow.

Inside NextSearch 2.3

One workspace for the work after migration

Migration workspace

Inspect indexes, aliases, shards, mappings, templates, pipelines, and document counts before traffic moves.

Query compatibility

Exercise match, count, field-capability, and custom JSON queries against the target while engineers resolve gaps.

Hybrid retrieval

Combine lexical, vector, semantic, and AI-assisted retrieval for site search, knowledge search, commerce, and RAG.

AI-assisted operations

Use the NextLLM Copilot for health checks, index discovery, operational questions, and guided administration.

Solr expertise remains part of the migration.

Nextbrick's published Apache Solr work covers SolrCloud session recovery, stable schema access, and Admin UI reliability. That context informs compatibility analysis, failure planning, and production support.
