How the migration works

  1. Discovery call

    We look at your current version, index sizes, query patterns and client libraries.

  2. Migration plan

    You get a written plan: target version, mapping changes, reindex strategy and rollback path.

  3. Cutover

    We help run the reindex and verify search results before traffic moves.

Frequently asked questions

Do I have to move my cluster to Bonsai to get help?

No! We'll tell you what the migration involves either way.

Which engine versions can you migrate from?

It depends on your plan. Tell us your current version on the form and we'll confirm compatibility, or see supported Elasticsearch and OpenSearch versions for the full tables.
