DTEX's OpenSearch Journey: From Migration to Innovation
summary
Shows a live migration using the OpenSearch Migration Assistant and its reindex-from-snapshot flow that takes snapshots from Elasticsearch (supports 1.x through 8.17) and reindexes into OpenSearch (demo to 2.x/3.2), preserving index settings and mappings and monitoring progress. Reports the new cluster runs 40% faster at about 80% of prior cost, migrates terabyte-scale product indices while aging hundreds of TB of logs via selective backfill, and replaces legacy Kibana plugins with a React/TypeScript plugin architecture that cuts testing effort ~70% and ships core plugins successfully.
