Amazon Aurora MySQL-Compatible Edition 3 (with MySQL 8.0 compatibility) now supports Percona Xtrabackup for completing physical migrations of your existing MySQL 8.x databases running on Amazon EC2 or outside of AWS. This capability makes it easier and faster to migrate large MySQL databases with complex schemas into Amazon Aurora MySQL. Percona XtraBackup allows you to perform consistent, non-blocking, online backups of your source MySQL database which can then be migrated to Aurora MySQL with minimal downtime.
