Follow these steps to change the IP address or network interface on an Azure Stateful node. This process ensures that the new configuration is applied correctly and network persistence is maintained.

1. In the console, go to Elastigroup > Stateful Nodes and select the node. 
2. Click Actions > Edit Configuration and toggle OFF Persist Network.
3. After network persistence is turned off, pause the SSN by navigating to Actions and clicking Paused.
4. Update the IP address using the API documented here: Azure Stateful Node Update API.
5. Resume the SSN.
6. Turn network persistence back ON.

The Azure Stateful node uses the updated IP address or network interface with network persistence re-enabled.
