- Introduced two new migrations (011b_recover_notification_services_rename and 011c_recover_auth_providers_rename) to check and recover the notification_services and auth_providers tables if they were incorrectly renamed during a previous migration. - Implemented logic to handle various states of the tables, including logging warnings for potential issues and ensuring safe recovery actions. - Updated the migration sequence to include these new recovery steps, enhancing the robustness of the database migration process.
