+# 🛠 Handling Log Analytics Workspace Deletion with Replication Enabled
+
+If redundancy (replication) is enabled for your Log Analytics workspace, you must disable it before deleting the workspace or resource group. Otherwise, deletion will fail.
+
+## ✅ Steps to Disable Replication Before Deletion
+Run the following Azure CLI command. Note: This operation may take about 5 minutes to complete.
+
+```bash
+az resource update --ids "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.OperationalInsights/workspaces/{logAnalyticsName}" --set properties.replication.enabled=false
+```
+
+Replace:
+- `{subscriptionId}` → Your Azure subscription ID
+- `{resourceGroupName}` → The name of your resource group
+- `{logAnalyticsName}` → The name of your Log Analytics workspace
+
+Optional: Verify replication disabled (should output `false`):
+```bash
+az resource show --ids "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.OperationalInsights/workspaces/{logAnalyticsName}" --query properties.replication.enabled -o tsv
+```
+
+## ✅ After Disabling Replication
+You can safely delete:
+- The Log Analytics workspace (manual)
+- The resource group (manual), or
+- All provisioned resources via `azd down`
