  "impact": "From 31 Mar 2028, the Azure App Service custom backup feature no longer backs up linked databases.

  "migration_path": "1. Implement a backup strategy for the databases linked to your App Service web applications before the retirement date.\n2. Use the native backup and restore tools available with the respective databases.\n3. For further information, see the [Microsoft guidance](https://aka.ms/AppSvcDBBkp).",
