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:
- Collections with URL patterns
- Start URLs and crawl rules

        assertEquals("testpass", defaultPassword, "Should delegate default password");
        assertEquals("jCIFS", nativeLanMan, "Should delegate native LanMan");

        verify(mockDelegate).getOemEncoding();
        verify(mockDelegate).getNetbiosHostname();
        verify(mockDelegate).getDefaultDomain();
        verify(mockDelegate).getDefaultUsername();
