#### Index Settings Migration

Fess uses OpenSearch/Elasticsearch internally, so you can:

1. Export index mappings and settings from source
2. Apply custom analyzers in Fess's `fess_config.properties`
3. Create synonym dictionaries in Fess's dictionary directory

### Apache Solr

For migrating from Apache Solr:

#### Document Export and Import

        final FessAdminAction action = createAction();

        final File testFile = new File(confDir.toFile(), "fess_config.properties");
        testFile.createNewFile();

        // Should not throw
        action.validateFilePath(testFile.getAbsolutePath());
    }

    @Test
