  "impact": "31 Jul 2032 is the RDS end of Extended Support date that AWS lists for MySQL 8.4. AWS states that once the RDS Extended Support period of a major engine version is over, Amazon RDS automatically upgrades the major engine version of a database not upgraded to a supported version. The pages do not state which version that automatic upgrade targets, or how soon after the end of the period it runs.\n\n- Major version upgrades can contain database changes that are not backward-compatible with existing applications.\n- A completed upgrade cannot be reverted to the previous engine version.\n- Minor versions can reach end of Extended Support earlier.\n- RDS Extended Support is a paid offering up to that date: see [Amazon RDS Extended Support charges](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/extended-support-charges.html).",
  "migration_path": "1. Test the upgrade first: create a DB snapshot of the DB instance, restore it to a new DB instance, and start a version upgrade on that new instance.\n2. Find the valid upgrade targets for the DB instance in the AWS Management Console or with the `aws rds describe-db-engine-versions` AWS CLI command. AWS lists the supported major version upgrades on its [MySQL on Amazon RDS versions](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MySQL.Concepts.VersionMgmt.html) page.\n3. If the DB instance uses read replicas, upgrade all of the read replicas before the source instance.\n4. Start the major version upgrade by modifying the DB instance, after following [Major version upgrades for RDS for MySQL](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.MySQL.Major.html).\n5. Downtime for the major version upgrade can be reduced with a blue/green deployment: [Using Amazon RDS Blue/Green Deployments for database updates](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/blue-green-deployments.html).\n6. Enrollment in RDS Extended Support ends the day an upgrade completes to an engine version that is still under RDS standard support. An upgrade to a version that is itself under RDS Extended Support does not end it: check the support dates of the target version in [Supported MySQL major versions on Amazon RDS](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MySQL.Concepts.VersionMgmt.html#MySQL.Concepts.VersionMgmt.ReleaseCalendar).",
