OpenSearch Consulting: Migration and Support Checklist
An OpenSearch consulting checklist for Elasticsearch migration, Amazon OpenSearch Service, security, performance, vector search, observability, and support.
Direct answer
An OpenSearch migration is ready when API, mapping, analyzer, plugin, security, snapshot, dashboard, client, and operational differences are documented and tested against real data and traffic. Version labels alone are not a compatibility plan; acceptance tests and rollback criteria are required.

Frequently asked questions
Do you support Amazon OpenSearch Service?
Yes. Consulting covers managed Amazon OpenSearch Service and self-managed OpenSearch, including migration, performance, security, vector search, observability, and operations.
Can OpenSearch replace Elasticsearch?
Often, but compatibility depends on versions, APIs, plugins, mappings, analyzers, security, clients, and operational requirements. We validate those factors before recommending a cutover.
Do you provide ongoing OpenSearch support?
Yes. Nextbrick provides production support, incident response, performance engineering, upgrades, and prepaid support credits.
