 ## Purge retained data
 
-If you set the data retention to 30 days, you can purge older data immediately by using the `immediatePurgeDataOn30Days` parameter in Azure Resource Manager. The purge functionality is useful when you need to remove personal data immediately. The immediate purge functionality isn't available through the Azure portal.
-
-Workspaces with a 30-day retention might keep data for 31 days if you don't set the `immediatePurgeDataOn30Days` parameter.
-
-You can also purge data from a workspace by using the [purge feature](personal-data-mgmt.md#exporting-and-deleting-personal-data), which removes personal data. You can't purge data from archived logs.
+If you need to retain data for 30 days for privacy compliance, [configure workspace retention](#configure-the-default-workspace-retention) to 30 days, then update workspace property `immediatePurgeDataOn30Days` to `true` using [REST](https://learn.microsoft.com/rest/api/loganalytics/workspaces/update). This operation isn't supported in CLI, PowerShell, and portal currently.
 
 > [!IMPORTANT]
-> The Log Analytics [Purge feature](/rest/api/loganalytics/workspacepurge/purge) doesn't affect your retention costs. To lower retention costs, decrease the retention period for the workspace or for specific tables.
