Amazon RDS Introduces Compatibility Checks for Upgrades from MySQL 5.7 to MySQL 8.0
Amazon Relational Database Service (RDS) now performs checks to confirm compatibility of your MySQL 5.7 database with MySQL 8.0, and stops the upgrade if incompatibilities are found.
RDS automatically looks for incompatibilities when you initiate an upgrade from MySQL 5.7 to 8.0. This capability helps you avoid unplanned downtimes, as the compatibility checks are performed before the instance is stopped for the upgrade. RDS sends you an RDS event notification whenever an incompatible upgrade is detected. You can review the PrePatchCompatibility log file generated by RDS for detailed information on each incompatibility and take actions to correct it.
Read more about database upgrade prechecks in our documentation. To initiate an upgrade from MySQL 5.7 to 8.0, visit the RDS console or download the latest AWS SDK or CLI.
