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

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

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:

 * governing permissions and limitations under the License.
