Support for In-Place Major Version Upgrade from 8.0 to 8.4
We previously announced that Azure Database for MySQL version 8.4 is now generally available. We’re now happy to share that in-place major version upgrade is supported for MySQL servers from 8.0 to 8.4. If you’re currently on MySQL 5.7, you’ll first need to perform an in-place upgrade from 5.7 to 8.0, and then upgrade from 8.0 to 8.4. Learn more.
Near-Zero-Downtime Maintenance - General Availability
You can now take advantage of near-zero-downtime maintenance for Azure Database for MySQL with high availability (HA) enabled. This capability is now generally available and is supported by our new HA architecture based on a dedicated Azure Standard Load Balancer design. Thanks to the dedicated Standard Load Balancer design, maintenance is now faster and no longer impacted by client-side DNS caching, which previously caused brief connection drops in some scenarios. This enhancement ensures that your mission-critical workloads remain continuously available, even during infrastructure updates, helping you meet strict uptime requirements and maintain operational continuity.
