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

### SIG-Azure

Sig Azure was focused on two primary new alpha features:
- Adding Azure Availability Zones support to cloud provider.
- Supporting Cross RG resources (disks, Azure File and node [Experimental]

Besides the above new features, support for Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is now stable and considered GA:
