### Google Search Appliance (GSA) / Google Mini

Fess provides comprehensive GSA migration support through configuration import and API compatibility.

#### Configuration Import

Fess can directly import GSA XML configuration files, automatically converting them to native Fess configurations.

**Step 1: Export GSA Configuration**

Export your GSA configuration as XML. A typical GSA configuration includes:

import org.xml.sax.helpers.DefaultHandler;

/**
 * Parser for Google Search Appliance (GSA) configuration files.
 * This SAX-based parser reads GSA XML configuration files and converts them into
 * Fess configuration objects including web crawling configurations, file crawling
 * configurations, and label types for access control.
 *
 * <p>The parser handles the following GSA configuration elements:
 * <ul>
 * <li>Collections with good/bad URL patterns</li>

 * governing permissions and limitations under the License.

 * configuration-related issues when working with GSA integration.
