Running the Single Server instance post sunset date would be a security risk, as there will be no security and bug fixes maintenance on the deprecated Single Server platform. To ensure our commitment toward running the managed instances on a trusted and secure platform post the sunset date, your Single Server instance, along with its data files, will be force-migrated to an appropriate Flexible Server instance in a phased manner.

We have sent recurring notifications over the past two years to complete the migration to Azure Database for MySQL Flexible Server, both via public channels such as Azure Update and blogs as well as direct outreach through customer emails, product pages, and Azure Portal banners. As part of our ongoing communication and assistance to migrate customers safely to their new environment, this section provides more information on the customer experience for any workloads that remain in production beginning 16th September 2024.

Starting 17th September, non-responsive servers which have an auto-migration scheduled and have not provided mandatory inputs will be stopped. Additionally servers with low TLS version, low client driver version and service endpoints will also be stopped. You'll be required to come to the Azure portal, acknowledge the migration actions and restart your server. Ensure to complete the action required in order to proceed with auto-migration, to avoid involuntary forced-migration later which could lead to server unavailability as only limited features can be migrated.

We strongly recommend using the [Azure Database for MySQL Import CLI](../migrate/migrate-single-flexible-mysql-import-cli.md) or [Azure Data Migration](../../dms/tutorial-mysql-Azure-single-to-flex-online-portal.md) Service to migrate to Azure Database for MySQL - Flexible Server before 16 September 2024 (read the [FAQ](./whats-happening-to-mysql-single-server.md#frequently-asked-questions-faqs) to learn more) to avoid any disruptions caused by forced migration and to ensure business continuity.

Post the sunset date, your Single Server instance, along with its data files, will be force-migrated to an appropriate Flexible Server instance in a phased manner. This might lead to limited feature availability as certain advanced functionality can't be force-migrated without customer inputs to the Flexible Server instance. This could lead to server unavailability. Read more about steps to reconfigure such features post force-migration to minimize the potential effect below.
