Cloud SQL is discontinuing support for legacy high availability (HA) instance configuration on January 6, 2025

## Deprecate Cloud SQL is discontinuing support for [legacy high availability (HA)](https://cloud.google.com/sql/docs/mysql/configure-legacy-ha) instance configuration on January 6, 2025\. After this date, you can't create Cloud SQL for MySQL instances with the legacy configuration for high availability. You also can't enable the legacy configuration for high availability on existing instances. Until January 6, 2025, legacy HA instances are still covered by the [Cloud SQL SLA](https://cloud.google.com/sql/sla). We recommend that you [upgrade your existing legacy HA instances](https://cloud.google.com/sql/docs/mysql/configure-legacy-ha#update-from-legacy) to regional persistent disk HA instances as soon as possible and create new HA instances using regional persistent disk instead. Starting on May 1, 2025, Cloud SQL will migrate any remaining instances that use the legacy HA configuration to the current HA configuration automatically.
