+If the certificate was originally generated by Microsoft (when using the *leaf_domain_label* to create the service), **it will automatically renew** when needed (This path doesn't work anymore, as V1 has been deprecated. You have to manually renew it). If you want to manually renew it, use one of the following examples to update the certificate:
 
 > [!IMPORTANT]
 > * If the existing certificate is still valid, use `renew=True` (SDK) or `--ssl-renew` (CLI) to force the configuration to renew it. This operation will take about 5 hours to take effect.
 > * When the service was originally deployed, the `leaf_domain_label` is used to create a DNS name using the pattern `<leaf-domain-label>######.<azure-region>.cloudapp.azure.com`. To preserve the existing name (including the 6 digits originally generated), use the original `leaf_domain_label` value. Do not include the 6 digits that were generated.
+> * Make sure do NOT pass `overwrite_existing_domain = true` when renewing certificate (default is false without passing it in the following example)
 
 **Use the SDK**
