For Azure, AWS RDS, and Aurora MySQL
The restore operation requires superuser privileges if the dump file contains the CREATE DEFINER statement for backups taken on a version lower than 10.2.
Backups taken on version 10.3 or higher cannot be restored using a version lower than 10.2.
Backup and restore are not supported if the only SSL connection is enforced at the server-level for the GCP MySQL workload.
You can restore a MySQL database to an alternate instance with another MySQL version than the backup instance, depending on MySQL's version compatibility.
