Migrate to Algolia from Elasticsearch, Typesense, or Meilisearch.
Covers data migration, query translation, replaceAllObjects zero-downtime swap,
and strangler fig traffic shifting.
Trigger: "migrate to algolia", "switch to algolia", "algolia migration",
"elasticsearch to algolia", "replace search engine", "algolia replatform".
Comprehensive guide for migrating from another search engine (Elasticsearch, Typesense, Meilisearch, or custom) to Algolia. Uses the strangler fig pattern: run old and new in parallel, gradually shift traffic, then cut over.
Prerequisites
A tested export of the source search data and a rollback owner for the cutover window.
An isolated target index or Algolia application for rehearsal.
Baseline relevance, latency, and record-count measurements for comparison after migration.

Instructions
Examples
The migration commands and comparison checks below illustrate a staged copy, validation, and cutover. Rehearse them against the target index before scheduling any production alias or frontend switch.
Step 1: Assess Current Implementation
# Find all search-related code
grep -rn "elasticsearch\|elastic\|typesense\|meilisearch\|\.search(" \
--include="*.ts" --include="*.tsx" --include="*.js" src/ | wc -l
# Inventory current search features used
grep -rn "aggregations\|facets\|filters\|sort\|highlight\|suggest" \
--include="*.ts" --include="*.tsx" src/
# Instant rollback: set traffic to 0%export ALGOLIA_TRAFFIC_PERCENT=0
# Restart services to pick up new env var# Or if fully cut over: old engine is still running, swap adapter# Keep old engine data in sync for at least 2 weeks after cutover
Output
The migration yields a verified target index with reconciled records, settings, and search behavior, plus a documented rollback point. It does not retire the source index until the acceptance checks pass.
