+**Migrating from Apache Solr**
+
+Migration Assistant supports migrating from Apache Solr 8.x to OpenSearch 3.x. This includes document backfill from Solr backups with automatic schema translation (Solr `schema.xml` field types to OpenSearch mappings). A Transformation Shim proxy is also available to help validate query compatibility between Solr and OpenSearch before making application changes. For details, see the [Solr Migration Overview](https://github.com/opensearch-project/opensearch-migrations/wiki/Solr-Migration-Overview).
